What is the acual length of an DNA strand in a influenza molecule?
92991
influenza is actually a single strand negative strand virus.\n\n\nand the genome is from 12,000 to 15,000 bases in length.

In DNA, the bases always appear in complimentary pairs - a DNA molecule is a double-strand of bases.  In this case, each C has a G stuck to it, so the # of each type will be the same.\n\nRNA is a single stranded molecule, so there are no matched pairs and there is no reason for the amount of any two bases to match.

its DNA it is a part of a gene which is a thing wich codes for something. it is a double stranded structure. its also called a polynucleotide.

One good one:\n\nDNA replication is much more resistant to errors ... so DNA molecules can be *much* longer than RNA and still survive replication.  This supports the stable propagation of a much larger number of genes (tens of thousands of genes) from generation to generation without degradation.

The differences between DNA/RNA:\n\n*DNA stays in the nucleus, while the mRNA leaves\n*RNA contains oxygen, while DNA doesn't (DEOXY- no oxygen)\n*DNA has the nitrogen bases Adenine, Thymine, Guanine, and Cytosine. RNA has those also, but instead of Thymine it has Uracil\n*RNA is single-stranded while DNA is double-stranded

The DNA is linked by the 4 bases G,C,A,T \nG and C pair together and A and T pair together they are held together by hydrogen bonds. G and C have 3 hydrogen bonds A and T have 2.\nThese form the double helix which is the DNA structure.

DNA has the form of a double helix. It is also anti parallel.

DNA is a chain of chemical "building blocks", called "bases", of which there are four types: these can be abbreviated A, T, C, and G. Each base can only "pair up" with one single predetermined other base: A+T, T+A, C+G and G+C are the only possible combinations; that is, an "A" on one strand of double-stranded DNA will "mate" properly only with a "T" on the other, complementary strand;\n\nA= Adenine\nT=Thymine\nC=Cytosine\nG=Guanine\n\nI got this from wikipedia

One really easy answer is DNA sequencing. Nanotechnology deals with objects measured in the billionths of a meter. Most say objects less than 100 nanometers. Therefore, although the length of a DNA Strand is way to long to be considered Nanotechnology the individual base pairs fit into nanotechnology perfectly.

A nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA. DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. The sequence of nucleotides determines individual hereditary characteristics.\n\nETYMOLOGY: \nd(eoxyribo)n(ucleic) a(cid)

Nucleotide = nitrogen base (purine or pyrimidine) + phosphate group + pentose sugar (ribose or deoxyribose)\nThey are units of DNA.\nNucleoside= nitrogen base(purine or pyrimidine)+ pentose sugar(ribose or deoxyribose)\nThey are units of RNA.\nHope u got it!

DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a "polynucleotide." Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group. There are four different types of nucleotides found in DNA, differing only in the nitrogenous base. The four nucleotides are given one letter abbreviations as shorthand for the four bases. \n\nA is for adenine \nG is for guanine \nC is for cytosine \nT is for thymine \nThe DNA backbone is a polymer with an alternating sugar-phosphate sequence. The deoxyribose sugars are joined at both the 3'-hydroxyl and 5'-hydroxyl groups to phosphate groups in ester links, also known as "phosphodiester" bonds

DNA's most amazing characteristic is that it will bind to itself in a very specific manner, forming a helix. Figure 1 illustrates two DNA molecules binding. The variable groups of the polymer interact with eachother to mediate this binding. Adenine interacts with Thymine and Cytosine interacts with Guanine. No other bonds are energetically favorable, for example Cytosine cannot bond with itself. The bonds that these variable groups form are called are called base pairs and are illustrated in Figure 2. Thus, by knowing the sequence of bases of one strand of DNA we immediately know the sequence of the DNA strand which will bind to it, this strand is called the reverse complement or just the complementary strand. In Figure 1 the right hand strand is the reverse complement of the left hand side and vice-versa.\n\n\nFrom G. S. Sent, Molecular Biology of Bacterial Viruses. Copyright 1963 by W. H. Freeman and Company\n\nFigure Two:Illustration of DNA basepairing. Thermodynamically the interactions Adenine, Guanine, Cytosine, and Thymine are driven by both the hydrophobic stacking interactions hydrogen bond interactions. The specificity of the base pairing is driven mainly by hydrogen bonding and stearic interference.\nThis relationship to the complementary strand has many implications that make life as we know it possible, and allows all sorts of molecular biology techniques. In one of the greatest understatements of all time Watson and Crick said it best in their original paper on the structure of DNA:\n\n"It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.".

Thymine pairs with Guanine.\nCytosine pairs with Adenine.\n\nThus, the complementary strand would be GGATCGA.

Oligonucleotides synthesized using the standard solid-state phosphoramidite method do not have phosphates at either the 5' or 3' end.  This should not be a problem for PCR.\n\nThe only time you need a phosphate at the 5' end is if you want to ligate that 5' end to a 3' end of another piece of DNA.  Remember that normal DNA ligation occurs between a 3'-OH and a 5'-P.  You can add the phosphate yourself using the enzyme polynucleotide kinase, or most commercial vendors that sell oligos will do it for you for an extra fee.

Yes, DNA is a polymer composed of four different nucleotides. The nucleotides are composed of phosphate and the sugar 2' deoxyribose, which make up the backbone of a molecule of DNA, and one of four nitrogenous bases: adenine (A), guanine (G), thymine (T), and cytosine (C). Bases on opposite DNA strands can form hydrogen bonds (A with T, and G with C), which hold the double-stranded molecule together. Polymerization of DNA occurs through the enzyme DNA polymerase, which catalyzes the synthesis of one of the DNA strands using the other strand as a template.
