Web17 mei 2024 · Explain the organization of the DNA molecule within the nucleus The nucleus is the largest and most prominent of a cell’s organelles (Figure \(\PageIndex{1}\)). The nucleus is generally considered the control center of the cell because it stores all of the genetic instructions for manufacturing proteins. WebAt the most basic level, DNA is wrapped around proteins known as histones to form structures called nucleosomes. The histones are evolutionarily conserved proteins that are rich in basic amino acids and form an octamer. The DNA (which is negatively charged because of the phosphate groups) is wrapped tightly around the histone core.
