From the data in Table 19.3, draw up a list of histone H3 modifications associated with gene activation. Then draw up a list of H3 modifications associated with repression.

Are these overlaps explained by different modifications?

Hello everyone and welcome to today's video. So which of the following modifications of Histone H3 is associated with the formation of hetero protein and gene silencing. Remember that when we form Hetero Comitan were pro preventing gene expression. So keep that in mind as we solve our problem. Let's go over answer choices and be first because we have a circulation. Remember that as circulation is heavily related to the formation of a chromatic which is going to promote gene expression. It is not going to be hetero chromatic informed here. So we're going to cancel both of these out. Then we have the we have the methylation of H three K 27. Well this is actually going to be related to gene silencing and it is going to be forming head or chromatic. However it is not going to be forming pure head or chroma team is going to be firming something called ulcerative hetero clementine which has many other properties because of this. We're going to cancel this out and then we have the methylation of H three K nine. This is going to be or correct answer choice because it is going to be related to gene silencing as methylation is but also it is going to be forming purely hetero commenting because of this. We're going to highlight answer choice e as the correct answer to our question. I really hope this video helped you and I hope to see you on the next one
