Regulation of Eukaryotic Gene Expression

Question 1

The regulation of many of the important genes in eukaryotes are regulated through what many mechanism?

Answer 1

regulating the rate of transcription

Question 2

Do histone acetylases favor gene expression or favor inactive chromatin?

Answer 2

favor gene expression

Question 3

Do histone deacteyltases for gene expression or favor inactive chromatin?

Answer 3

inactive chromatin

Question 4

What type of amino acid is acetylated for gene expression in the histones that are associated with chromatin? Why?

Answer 4

The lysyl residues are acetylated. This decreases the positive charge contributed by the histone structure resulting in a poor interaction between the DNA and the histone proteins

Question 5

What general region of the DNA associated with the chromatin during the process of gene expression must be exposed?

Answer 5

promoter region

Question 6

What is an important transcription factor that plays major role in gene expression for eukaryotes?

Answer 6

TFIID
