Study Notes

DNA Overview

DNA stands for deoxyribonucleic acid, which is the hereditary material in all living organisms.
Found within the nucleus of eukaryotic cells and in the nucleoid region of prokaryotic cells.

Replication Process

DNA has the ability to replicate itself, ensuring genetic continuity.
When cells divide, each new cell receives an exact copy of the DNA from the parent cell.

Role in Heredity

DNA carries genetic information necessary for the growth, development, and functioning of living organisms.
It is crucial for transmitting traits from one generation to the next.
