Exam 4 Chapter 16 Part 1 of 1 - 9.33/ 10.0 Points Question 1 of 10 1.0/ 1.0 Points Epigenetics refers to a special kind of hereditary mechanism. Epigenetic changes do not change the DNA nucleotide sequence, yet their effect on gene expression can last for several generations. In one surprising study, it was found that the grandsons of men who suffered a famine were less likely to die of cardiovascular disease. The experience of famine made some cardio-protective change in the sperm of those grandfathers that was passed on. What type of change was likely responsible? A. ubiquitin tagging B. histone acetylation or DNA methylation C. phosphatase levels D. transcription factor activity

Feedback:Learning Objective Text: Analyze the processes of gene expression and gene regulation Question 3 of 10 1.0/ 1.0 Points In eukaryotes, where would a protective modification be found on mRNA?
Feedback:Correct Question 4 of 10 1.0/ 1.0 Points
A gene is made up of three exons (numbered consecutively) with two introns (intron 1 between exons 1 and 2 and intron 2 between exons 2 and 3). What would happen if there were a mutation at the 3’ splice site of intron 1?
Feedback:Correct Question 5 of 10 1.0/ 1.0 Points _________ is the first protein to bind to mRNA to being initiation of translation. A. TFIIA B. eIF-2
C. TFIID D. 60S ribosomal subunit E. 40S ribosomal subunit Question 6 of 10 1.0/ 1.0 Points Enhancers located hundreds of bases upstream of a gene can be brought to the promoter by _________.
