Question

which of the following has the capacity to inhibit transcription? group of answer choices silencers chromatin structure enhancer mutations all of these can inhibit transcription methylated cytosines

Answer 1

Silencers, chromatin structure, enhancer mutations, and methylated cytosines can all inhibit transcription.

Step-by-step explanation:

The capacity to inhibit transcription can be found in various factors. Silencers are cis-acting DNA elements that bind repressor proteins, preventing the initiation of transcription. Chromatin structure can also influence transcription by either opening or closing the chromosomal region encoding a gene. Enhancer mutations can disrupt the binding of transcription factors to enhancers, leading to a reduction in transcription. Lastly, methylated cytosines in CpG islands can result in gene silencing by preventing transcription factor binding.

Answer 2

The option that has the capacity to inhibit transcription is E. all of these can inhibit transcription

Silencers, chromatin structure, and enhancer mutations can all inhibit transcription by preventing RNA polymerase from accessing the DNA template. Methylated cytosines can also inhibit transcription by making the DNA less accessible to RNA polymerase.

So, Chromatin structure is the way that DNA is packaged in the nucleus. DNA is wrapped around proteins called histones to form chromatin. The tightness of chromatin packaging can affect transcription.
