- Which of the following statements most accurately represent chromatin state and transcription? Group of answer choices 1.Histone deacetylases promote closed chromatin and result in repressed transcription 2.Open chromatin is associated with hypoacetylation and has high levels of transcription 3.Histone acetyltransferases result in hypoacetylation and high levels of transcription 4.Hyperacetylation is associated with closed chromatin and low levels of transcription__________ binds to DNA during S phase and maintains the linkage between sister chromatids following DNA replication : a) cohesins b) condensins c) Aurora d) Cdk4Discuss the differences between the compaction levels of metaphase chromosomes and those of interphase chromosomes. Whenwould you expect gene transcription and DNA replication to takeplace, during M phase or interphase? Explain why
- please fill in the blank When the cell goes from M to GI, the number of nucleosomes on this stretch of DNA should ------, and the width of the chromatin fiber should -------. Please select one Newly made lamins should ( single peptide = SP), or (nuclear localization = NLS) or (Transit peptide =TP) or ( Transmembrane domain) or ( SP and NLS) or ( SP or TP) or (transcription activating domain) or ( None of these)Suppose a mutation occurs in the gene encoding eukaryotic RNA polymerase 1, 2 , or 3 that renders that polymerase nonfunctional. Match each RNA polymerase with all of the cellular processes that it would disrupt.The diagram below shows the structure of DNA from the level of a gene to a condensed mitotic chromosome. At each of the four locations marked, indicate how a gene may be regulated by selecting from the choices given. Some answer choices may fit into more than one position; however, you should use each answer choice only once. Choices given: Alternative splicing within the gene sequence can lead to different forms of mRNA. A promoter region can be blocked by another protein. Histone deacetylation can prevent DNA from unwinding. A regulatory region can be bound and increase transcription rates.
