Which of the following predictions could you make about a cell in which the HP1 protein were disabled?
A)Methylation of DNA would increase.
B)The entirely of the cell's chromosomes would be condensed into heterochromatin.
C)Histone methyltransferase would bind to chromatin more easily.
D)Heterochromatin would not be formed.

Question

Quizplus · Accepted Answer

HP1 protein is involved in forming heterochromatin, which is a condensed form of chromatin. Therefore, disabling HP1 protein would result in the inability to form heterochromatin, making choice D the correct option. Methylation of DNA may or may not increase depending on other factors, histone methyltransferase binding may or may not be affected by HP1 protein, and the entire cell's chromosomes condensing into heterochromatin is highly unlikely.
