A particular cell contains all of the standard histones but lacks several histone variants. Which of the following MAY be true of this cell?

Question

Quizplus · Accepted Answer

Histone variants play important roles in regulating gene expression by influencing chromatin architecture and modulating accessibility of DNA-binding proteins to specific sets of genes. If a cell lacks certain histone variants, it may lead to altered gene expression patterns and the cell may express different sets of genes compared to other cells in the same organism. However, it does not necessarily mean that the cell will be completely unable to remodel its chromatin, have an enhanced ability to chemically modify its histones, be unable to express any of its genes at all, or not be able to divide.
