Question:
Examples of nucleic acids are DNA and RNA.

Expert Verified Solution:

Nucleic acids are essential macromolecules found in all living organisms, playing a crucial role in storing and transmitting genetic information. The two primary examples of nucleic acids are DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid).

DNA: DNA is the molecule that carries the genetic blueprint of an organism. It contains the instructions needed for the growth, development, functioning, and reproduction of all living things. DNA is a double-stranded helix, with each strand composed of a long chain of nucleotides.

RNA: RNA is a single-stranded molecule that is involved in various roles within the cell, including acting as a messenger between DNA and the protein synthesis machinery. There are different types of RNA, such as mRNA (messenger RNA), tRNA (transfer RNA), and rRNA (ribosomal RNA), each with specific functions in the process of translating genetic information into proteins.

Nucleic acids like DNA and RNA are fundamental to life, as they ensure the continuity of genetic information from one generation to the next and enable the expression of that information within cells.
