i am not 100 on this but i thinkk it is B
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.
The first reason that in 1940 there was one person and the other reason is a 1941 there was two persons so that’s the answer
<span>the microscope that Anton van Leeuwenhoek use to observe single-celled organisms is : a very simple microscope, which is the type of microscope that only has one lens.
