Patient's question:
High, can't have children, how did this happen?Doctor's answer:
In the nucleus of biological cells, there is a substance that is easily stained by alkaline dyes, called chromatin. Chromosomes are just another form of chromatin. Their composition is the same, but because of the different structures, there are still certain differences. Chromosomes are formed by the spiraling of chromatin during the interphase of cell mitosis. The chromatin in prokaryotic cells used for chemical analysis contains naked DNA, which means it is not connected to other types of molecules. However, eukaryotic chromosomes are much more complex, consisting of four types of molecules: DNA, RNA, histones (low molecular weight alkaline proteins rich in lysine and arginine, with at least five different types), and non-histones (acidic). The ratio of DNA to histone is close to 1:1.
