Detailed explanation-1: -Nucleic acids are key macromolecules in the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Detailed explanation-2: -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-3: -Nucleic acids are molecules made up of nucleotides that direct cellular activities such as cell division and protein synthesis.
Detailed explanation-4: -The natural nucleic acids DNA and RNA serve as the repositories and carriers of genetic information for all life on earth.
Detailed explanation-5: -RNA has three main roles in the cell: It carries the instructions from the DNA in the nucleus to the ribosomes where proteins are made in the cytoplasm of the cell.
