chromatin vs. chromatid: What's the difference?

Chromatin refers to a substance found in the cell nucleus that’s composed primarily of DNA and proteins. When cells divide, chromatin condenses to form chromosomes which split into two identical strands called chromatids. Each chromatid then becomes a chromosome in each new cell that is formed.

chromatin

noun

chromatid
