chromatin vs. chromosome: What’s the difference?

Chromatin is a substance found in the cell nucleus that’s composed primarily of DNA and proteins. When cells divide, chromatin condenses to form chromosomes, threadlike structures that consist of a single molecule of DNA. The chromosome is what carries the genes (in humans, it holds 23 pairs of genes).

[ kroh-muh-tin ]

[ kroh-muh-sohm ]
