Question

Regulation of Gene Expression in Eukaryotes Part A -Modification of chromatin structure Which statements about the modification of chromatin structure in eukaryotes are true? Select all that apply. View Available Hint(s) Acetylation of histone tails is a reversible process Some forms of chromatin modification can be passed on to future generations of cells. DNA is not transcribed when chromatin is packaged tightly in a condensed form. O Acetylation of histone tails in chromatin allows access to DNA for transcription. Deacetylation of histone tails in chromatin loosens the association between nucleosomes and DNA Methylation of histone tails in chromatin can promote condensation of the chromatin Submit Part B Regulation of transcription initiation toh f D includes the fantasin gene, along with it

Explanation / Answer

PART A. Correct statements are :

However, Deacetylation of histone tails in chromatin does not loosen nucleosome association with DNA.

PART B: correct statement are:

NOTE: both the genes will express at normal levels when the general transcription factors are present in the cell. Also, oth the genes do not have identical enhancer, they only have a common control element C in their enhancer. Rest of the staments are false.
