A cell is homozygous for a LOF mutation in the histone acetyltransferase (HAT) gene. Which of the following is/are true? a. Chromatin in the cell will be more condensed than usual, decreasing expression of genes that should be expressed. b. This will lead to histones with more positive charges on their tails, increasing the interaction between histones and the DNA backbone. c. This will lead to a decrease in DNA methylation and therefore cause an increase in gene expression. d. Chromatin in the cell will be less condensed than usual, increasing expression of genes that should not be expressed.
