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.

If not, how can you reconcile these differences?

Hello everyone and welcome to today's video. So which his stone age three modification is necessary for the chrome 18 remodeling complexes to be recruited to the promoter regions of the genes. Let's go over Each of our answer choices so that we may solve this problem. Let's begin by answer choice. The phosphor relation of age three is 10. Or remember from previous videos that the phosphor relation of this region is going to be a post transcription modification. Because of this it is not going to be involved in their recruiting of these chromatic remodeling complexes. So we're going to cancel this. Then we have B and C. The assimilation of H three K nine and the methylation of H three K 36. These have been actively found to be involved in gene expression. However, there is no evidence that they are necessary for chromatic remodeling complexes to be recruited. So we're going to cancel both of them out. Then we have methylation of H three K four. This is going to be or correct answer choice because this age three modification is going to be necessary for cremating remodeling complexes to be recruited to the promoting regions of genes. So we're going to highlight that as the correct answer to our question. I really hope this video helped you and I hope to see you on the next one
