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.

The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine.

They hold the information to build and maintain an organism's cells and pass genetic traits to offspring. A gene consists of a long combination of four different nucleotide bases namely adenine, cytosine, guanine and thymine. All living things depend on genes as they specify all proteins and functional RNA chains.

DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine.

There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine).

The main role of DNA in the cell is the long-term storage of information. ... The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA.

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.

DNA. The vast majority of organisms encode their genes in long strands of DNA (deoxyribonucleic acid). DNA consists of a chain made from four types of nucleotide subunits, each composed of: a five-carbon sugar (2-deoxyribose), a phosphate group, and one of the four bases adenine, cytosine, guanine, and thymine.

The four bases found in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). These four bases are attached to the sugar-phosphate to form the complete nucleotide, as shown for adenosine monophosphate.

The only role of DNA polymerase I is to hydrolyse the RNA primer and fill in the gaps with complementary deoxyribonucleoside triphosphates and the end of DNA replication. DNA polymerase III has 3 functions: Selects and adds free deoxyribonucleoside triphosphates complementary to the DNA template strand.

List the chemical components of DNA. Nucleotides, each with a deoxyribose molecule (5-carbon sugar molecule), a phosphate group, and a nitrogen-containing base. The four bases are adenine (A), thymine (T), guanine (G), and cytosine (C).

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. Each new strand of DNA contains an old stand from the original.

The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.
