While much remains to be learned about the role of nucleosomes
and chromatin structure and function, recent research indicates
that in vivo chemical modification of histones is
associated with changes in gene activity. One study determined that
acetylation of H3 and H4 is associated with 21.1 percent and 13.8
percent increases in yeast gene activity, respectively, and that
histones associated with yeast heterochromatin are hypomethylated
relative to the genome average [Bernstein et al. (2000)].
Speculate on the significance of these...

Which statements about the modification of chromatin structure in eukaryotes are true? 2 pts a. Acetylation of histone tails in chromatin allows access to DNA for transcription. b. Histone proteins are always permanently placed along a DNA sequence but the binding to DNA can be loosened. c. Methylation of DNA is associated with the gene activation. d. Acetylation of histone tails is a reversible process. e. Some forms of chromatin modification can be passed on to future generations of cells.

Identify the most accurate term related to chromatin remodeling. DNA is associated with proteins to form. A is compsed of DNA wrapped around an octamer of histone proteins. An activator can increase transcription by attracting a to the region. Addition of (-COCH_3) groups to histone amino terminal tails results in a/an in gene expression. Removal of acetyl groups from histones results in a/an in gene expression.

Part 1. Eukaryotes use at least two distinct mechanisms to control gene expression by altering the structure of chromatin around a particular gene. One of these mechanisms is the covalent modification of histones to switch DNA between an open and closed confirmation. A second mechanism is the covalent modification of DNA (typically on cytosines) by methylation. A. Describe a type of histone modification and explain what effect is has on chromatin, and how that effect is achieved. a. One type...

Which of the following is not true regarding regulation of gene expression in eukaryotes? In eukaryotic cells, transcriptional activators often work by recruiting the transcriptional macinery to gene promoters DNA methylation is an example of an epigenetic mark that can be inherited Acetylation of histones can result in a more open chromatin structure to allow transcription to occur Different genes can be turned off or on between different organs or stages of development Transcription factor DNA sequences are bound by...
