검증된 단계별 안내1
Understand that chromatin is a complex found in the nucleus of eukaryotic cells, primarily composed of DNA and proteins.
Recall that the proteins associated with chromatin are mainly histones, which help package and organize DNA into a compact structure.
Note that the problem states chromatin is approximately 40% DNA, so the remaining major component must be proteins.
Recognize that lipids, carbohydrates, and RNA molecules are not the primary components of chromatin structure.
Conclude that chromatin is composed of about 60% proteins, mainly histones, complementing the 40% DNA content.
