Nuclear?  Nuclear envelope?  Nuclear membrane? \n\nThe word 'eukaryote' means 'true nuclei'.  They are talking about the membrane which surrounds the nucleus of the cell.  This is not present in Prokaryotes.

There are two general classes of cells: prokaryotic and eukaryotic. The evolution of prokaryotic cells preceded that of eukaryotic cells by 2 billion years.\n\nHumans, of course, are an example of multicellular eukaryotes. \nThe major similarities between the two types of cells (prokaryote and eukaryote) are: \nThey both have DNA as their genetic material. \nThey are both membrane bound. \nThey both have ribosomes . \nThey have similar basic metabolism . \nThey are both amazingly diverse in forms. \nThe major and extremely significant difference between prokaryotes and eukaryotes is that eukaryotes have a nucleus and membrane-bound organelles , while prokaryotes do not. The DNA of prokaryotes floats freely around the cell; the DNA of eukaryotes is held within its nucleus. The organelles of eukaryotes allow them to exhibit much higher levels of intracellular division of labor than is possible in prokaryotic cells. Additional obvious differences between prokaryotes and eukaryotes include: \n\nSize \nEukaryotic cells are, on average, ten times the size of prokaryotic cells. \nGenomic composition and length \nThe DNA of eukaryotes is much more complex and therefore much more extnsive than the DNA of prokaryotes. \nCell Wall \nProkaryotes have a cell wall composed of peptidoglycan, a single large polymer of amino acids and sugar . Many types of eukaryotic cells also have cell walls, but none made of peptidoglycan. \n\n\nCell theory :\n1.All organisms are made up of one or more cells. \n2.The cell is the fundamental unit of structure and function in living things. \n3.All cells are essentially the same in chemical composition

DNA stands for DEOXYRIBONUCLEIC ACID.\nITs one of the type of Nucelic acid.In order to understand the role of DNA its important to understand the structure of DNA in a cell.In prokaryotes-DNA IS NOT ENCLOSED IN A NUCLEUS.Whereas in Eukaryotes-DNA is enclosed in a nucleus.\nSince you want to understand the structure of DNA.\nlets look at its components first\nmonomer of DNA IS NUCLEOTIDE\neach nucleotide is made up of Deoxyribose sugar,Phosphate group and any of the 4 nitrogenous base I.E. ADENINE(A)\nGuanine(G),Thymine(T) and Cytosine(C).Base pairings A-T AND G-C ALWAYS.\nPrimary structure of DNA IS  like a ladder structure and then it forms the DOUBLE HELIX STRUCTURE AND THEN IT GOES TO super coil stage known as Tertiary structure and last is Quartenary structure or chromosome stage, you don't always see DNA in its quartenary stage only when its undegoing cell division otherwise mostly you will see DNA in a supercoil state i.E. Tertiary stage.

Prokaryotes make 38 ATP from complete oxidative breakdown of one Glucose molecule. Eukaryotes (cells with nuclei) make 36 because they hae to spend one ATP to transport both of the NADPH molecules that are created in the cytoplasm during glycolysis into the mitochondria to be used in the Electron Transport Chain.

They are called eukaryotic cells.

DNA is what makes up our genes.  It is several long chains (polymers) of molecules that contain a 'chemical code' that the body uses to make proteins (proteins are many types of molecules that are necessary for the body to make and run itself).  These long chains of DNA are grouped into 23 different chromosomes.  You have two pairs of each chromosome - one set of 23 from your mom and the other set of 23 from your dad.  So, in total, you have 46 chromosomes in each cell.\n\nEach cell in your body has the same DNA.  But a liver cell is different from a skin cell, etc.  That is because each cell type has access to only certain genes in your DNA (to make the proteins needed specifically for that type of cell).\n\nStructurally, DNA looks like a flexible ladder (like a rope ladder).  The runs of the ladder (the sides) are the long chains or polymers and consist of a sugar group connected to a phosphate group, connected to the next sugar group, and so on.  Between these side chains are pairs of 'bases' - Adenine, Thymine, Guanine, and Cytosine (A T G  C).  These are the actual code that contains the information in your genes.\n\nThe 'ladder' of DNA twists around itself to form a shape called a 'double helix'.\n\nI hope this is helpful to you.  Good luck!

I don't think so becasue prokaryotes means ''primitive cell'' so eukaryotes come form themm they are ''true cells''. \n\n2. electorn microscoep,- advantges: 3d images, very high resolution.\ndisadvanteges: long time to prepare sample, sample most be dead, electron micrsocope are expensive, and the images are in black and white.\n\n I you want to know how a susbtance enters a cells is better with a light microscope because you cant have a life cell. but i think you could still study it with electron. But take in consideration that disavantages i told you.

B) Membrane-bound organelles\nThe procariotic cells are like a water-filled baloon, they are just a cover with water and other things (of course, this is only an example), while eukaryotic cells have compartiments.\nEvery cell has DNA, that's the way information is passed from cell to cell when they reproduce.\nRibosomes are important for producing proteins, every cell has to have them, even if with time they lose them.\nCytoplasm is the 75% of every cell, it's basically water, proteins and other things.

There are many different kinds of cells. Eukaryotic (mostly all animal, fungi, and plant cells), Prokaryotic (bacteria), and then there are specialized cells in most organisms. I.E. storage cells, bacteria-fighting cells, hormone producing and recieving cells. I am not sure that there is a set number of different kinds. However, the Prokaryotic and Eukaryotic division is the beginning of differentiation among all cells. It is used to help differentiate different kingdoms of organisms.

Deoxyribonucleic acid (DNA) is a nucleic acid —usually in the form of a double helix— that contains the genetic instructions specifying the biological development of all cellular forms of life, and most viruses. DNA is a long polymer of nucleotides (a polynucleotide) and encodes the sequence of the amino acid residues in proteins using the genetic code, a triplet code of nucleotides.\nIn complex eukaryotic cells such as those from plants, animals, fungi and protists, most of the DNA is located in the cell nucleus. By contrast, in simpler cells called prokaryotes, including the eubacteria and archaea, DNA is not separated from the cytoplasm by a nuclear envelope. The cellular organelles known as chloroplasts and mitochondria also carry DNA.\nDNA is often referred to as the molecule of heredity as it is responsible for the genetic propagation of most inherited traits. In humans, these traits can range from hair colour to disease susceptibility. During cell division, DNA is replicated and can be transmitted to offspring during reproduction. Lineage studies can be done based on the facts that the mitochondrial DNA only comes from the mother, and the male Y chromosome only comes from the father.\nEvery person's DNA, their genome, is inherited from both parents. The mother's mitochondrial DNA together with twenty-three chromosomes from each parent combine to form the genome of a zygote, the fertilized egg. As a result, with certain exceptions such as red blood cells, most human cells contain 23 pairs of chromosomes, together with mitochondrial DNA inherited from the mother.\n\nMolecular structure:\nAlthough sometimes called "the molecule of heredity", DNA macromolecules as people typically think of them are not single molecules. Rather, they are pairs of molecules, which entwine like vines to form a double helix (see the illustration at the right).\nEach vine-like molecule is a strand of DNA: a chemically linked chain of nucleotides, each of which consists of a sugar (deoxyribose), a phosphate and one of five kinds of nucleobases ("bases"). Because DNA strands are composed of these nucleotide subunits, they are polymers.\nThe diversity of the bases means that there are five kinds of nucleotides, which are commonly referred to by the identity of their bases. These are adenine (A), thymine (T), uracil (U), cytosine (C), and guanine (G). U is rarely found in DNA except as a result of chemical degradation of C, but in some viruses, notably PBS1 phage DNA, U completely replaces the usual T in its DNA. Similarly, RNA usually contains U in place of T, but in certain RNAs such as transfer RNA, T is always found in some positions. Thus, the only true difference between DNA and RNA is the sugar, 2-deoxyribose in DNA and ribose in RNA.\nIn a DNA double helix, two polynucleotide strands can associate through the hydrophobic effect and pi stacking. Specificity of which strands stay associated is determined by complementary pairing. Each base forms hydrogen bonds readily to only one other, A to T forming two hydrogen bonds and C to G forming three hydrogen bonds. The GC content and length of each DNA molcule dictates the strength of the association; the more complementary bases exist, the stronger and longer-lasting the association characterised by the temperate required to break the hydrogen bonding, its Tm value.\nThe cell's machinery is capable of melting or disassociating a DNA double helix, and using each DNA strand as a template for synthesizing a new strand which is nearly identical to the previous strand. Errors that occur in the synthesis are known as mutations. The process known as PCR (polymerase chain reaction) mimics this process in vitro in a nonliving system.\nBecause pairing causes the nucleotide bases to face the helical axis, the sugar and phosphate groups of the nucleotides run along the outside; the two chains they form are sometimes called the "backbones" of the helix. In fact, it

Nature has determined this design to be the most efficient and useful for higher order organisms.  There are two types of cell "designs", prokaryotic (bacteria) and eukaryotic (plant and animal cells).  It is thought that at one point all living things were prokaryotic, then at some point in our evolution a nuclear envelope was developed and proved to be beneficial to the organism, thereby natural selection allowed for the continuation of a nuclear envelope.  As time went by plants and animals both evolved from some ancestor of this first eukaryotic cell and henceforth have similar cell designs.  As for the actual benefits of this design, the nuclear envelope of plant and animal cells serve to protect the DNA, and therefore genes, of the animal from damage, and also serves as a type of filter seperating cellular processess in the cytosol from gene regulation in the nucleus.
