Essential biomolecules that store, transmit, and express genetic information through their unique chemical structures and base-pairing properties.

Nucleic Acids

Nucleic acids are fundamental Macromolecules that serve as the molecular basis for genetic information storage and transmission in all known living organisms. Their discovery and characterization revolutionized our understanding of Cellular Organization and heredity.

Chemical Structure

Basic Components

Nucleotides - the building blocks consisting of:
- A pentose sugar (ribose or deoxyribose)
- A phosphate group
- A nitrogenous base
Phosphodiester Bonds form the backbone
Hydrogen Bonds enable base pairing

Types of Nucleic Acids

DNA (Deoxyribonucleic Acid)

Double-helix structure
Contains genetic instructions
Located primarily in the Nucleus
Uses bases: Adenine, Thymine, Cytosine, Guanine

RNA (Ribonucleic Acid)

Usually single-stranded
Multiple functional types:
- Messenger RNA (mRNA)
- Transfer RNA (tRNA)
- Ribosomal RNA (rRNA)
- Non-coding RNA
