Answer:
The correct answer is c the mutant will show decreased levels of gene expression.
Explanation:
Histone acetyl transferase is an enzyme that helps in the transfer of acetyl group to the epsilon -NH2 group of lysine reside of histone proteins that surrounds the DNA molecule of chromosome.
This results to make the target DNA more assecible for transcription mediated by RNA polymerase resulting the gene expression.
On the other hand the mutant in which histones are not acetylated,transcription rate decreases as the non acetylated DNA is less assecible to RNA polymerase.
Precipitation is your answer hope this helps pls thank me
The statement about boiling points that is true is the boiling point of a substance is higher than its freezing point.
If something boils, it means it is really hot in there, and if it freezes, it is very cold.
