Detailed explanation-1: -Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.

Detailed explanation-2: -The natural nucleic acids DNA and RNA serve as the repositories and carriers of genetic information for all life on earth.

Detailed explanation-3: -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.

Detailed explanation-4: -Due to its deoxyribose sugar, which contains one less oxygen-containing hydroxyl group, DNA is a more stable molecule than RNA, which is useful for a molecule which has the task of keeping genetic information safe. RNA, containing a ribose sugar, is more reactive than DNA and is not stable in alkaline conditions.

Detailed explanation-5: -A major function of nucleic acids involves the storage and expression of genomic information. Deoxyribonucleic acid, or DNA, encodes the information cells need to make proteins.
