Study Notes

Chromosomes

The nucleus contains genetic information, organized into chromosomes, which are DNA coils.
A gene is a specific DNA section coding for a protein, thus controlling characteristics. Each chromosome carries many genes.
Body cells have 23 pairs of chromosomes (46 total), inheriting one from each parent.
Sex cells (gametes) have half the number of chromosomes (23 total), unlike other body cells.
