LIFE SCIENCE

Detailed explanation-1: -Deoxyribonucleic acid (DNA) is a molecule that encodes an organism’s genetic blueprint. In other words, DNA contains all of the information required to build and maintain an organism.

Detailed explanation-2: -In nature, just two closely related nucleic acids, DNA and RNA, function as repositories and carriers of genetic information.

Detailed explanation-3: -Nucleic acids are polymers that store, transmit, and express hereditary (genetic) information. This information is encoded in the sequences of monomers that make up nucleic acids. There are two types of nucleic acids: DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA stores and transmits genetic information.

Detailed explanation-4: -DNA stores biological information in sequences of four bases of nucleic acid-adenine (A), thymine (T), cytosine (C) and guanine (G)-which are strung along ribbons of sugar-phosphate molecules in the shape of a double helix.
