Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.

DNA contains only four bases, called A, T, C and G. The sequence of the nucleotides along the backbone encodes genetic information. The four roles DNA plays are replication, encoding information, mutation/recombination and gene expression.

Describe the structure and function of DNA. FUNCTION: Holds genetic code/info/ genes and instructions for making proteins. What is the process of DNA replication? The double Helix unzips and new nitrogen bases are added to create a new strand of DNA to create a new cell.

All of the information needed to build and maintain an organism — whether it's a human, a dog, or a bacterial cell — is contained in its DNA. DNA molecules are composed of four nucleotides, and these nucleotides are linked together much like the words in a sentence.

The function of the nucleus is to regulate gene expression, including controlling which proteins the cell makes. In addition to DNA, the nucleus contains a thick liquid called nucleoplasm that is similar in composition to the cytosol found in the cytoplasm outside the nucleus (Figure 5.6.

The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.

DNA is contained in blood, semen, skin cells, tissue, organs, muscle, brain cells, bone, teeth, hair, saliva, mucus, perspiration, fingernails, urine, feces, etc.

The main function of DNA polymerase is to make DNA from nucleotides, the building blocks of DNA. There are several forms of DNA polymerase that play a role in DNA replication and they usually work in pairs to copy one molecule of double-stranded DNA into two new double stranded DNA molecules.

Functions of Nucleus The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. It controls the hereditary characteristics of an organism. The organelle is also responsible for protein synthesis, cell division, growth, and differentiation.

Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.

What is the function of the nucleus? contains nearly all the cells DNA and with it the coded instructions for making proteins and other important molecules.

The most important function of chromosomes is to carry the basic genetic material – DNA. DNA provides genetic information for various cellular functions. These functions are essential for growth, survival, and reproduction of the organisms. Histones and other proteins cover the Chromosomes.

A gene can be described as: a series of DNA bases that contain information for production of a protein.

Nucleotides. Possibly the first biomolecules to support life, nucleic acids store and transfer cellular information and transfer energy in all living organisms. Deoxyribonucleic acid, better known as DNA, stores hereditary information in small segments called genes inside long polymer strands.
