NURSING ANM AND GNM

Detailed explanation-1: -The human genome (all the DNA of an organism) consists of around three billion nucleotides divided up between 23 paired DNA molecules, or chromosomes. The information stored in the order of bases is organized into genes: each gene contains information for making a functional product.

Detailed explanation-2: -The function of DNA is to store all of the genetic information that an organism needs to develop, function, and reproduce. Essentially, it is the biological instruction manual found in each of your cells. The instructions in DNA are written in a simple alphabet that has just four letters-A, T, C, and G.

Detailed explanation-3: -Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs.

Detailed explanation-4: -Nucleotides have a central role in the physiology of organisms as building blocks of nucleic acids, storage of chemical energy, carriers of activated metabolites for biosynthesis, structural moieties of coenzymes, and metabolic regulators.

Detailed explanation-5: -Nucleotides are in particular essential for replication of DNA and transcription of RNA in rapidly dividing stages. Nucleotides are also essential in providing the cellular energy sources (ATP and GTP), and are involved in numerous other metabolic roles.
