Answer:
2. muscular system and cardiovascular system
Answer:
option 1
Explanation:
In assemblying the nucleosome, this reaction occurs in two main steps. the H3 and H4 are recruited first to the DNA in pairs forming the H3/H4 tetramer; meaning two of H3 and two of H4. This gives rise to the nucleosome precursor. Then after this, the dimers of both H2A/H2B are recruited to this precursor, to give rise to the octamer structure around which the DNA is wrapped.
The answer is b. because you wouldn't want a daughter cell that didn't have <em>all </em>necessary to be a complete cell, and this could be messed up if the DNA didn't replicate prior to cell division
