Which are the two main types of nucleic acids?

• A. DNA and RNA
• B. RNA and Proteins
• C. DAN and RNA
• D. Proteins and Lipids

Answer: (A)

Nucleic acids are essential macromolecules found in all living organisms, and they play crucial roles in the storage and transmission of genetic information. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA serves as the long-term storage medium for genetic information and is structured as a double helix made up of nucleotide sequences that carry the instructions required for the development and functioning of all living organisms. RNA, on the other hand, plays several roles in the process of translating this genetic information into proteins and carries out various functions in the cell, including messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). The presence of DNA and RNA as the primary nucleic acids underscores their foundational role in genetics, cellular processes, and the overall functioning of biological systems. Other molecules like proteins and lipids, while critical for cellular structure and function, do not classify as nucleic acids and therefore do not represent the core types under discussion.
