Question 1

Through control of gene expression, a bacterial cell responds to changing __________ conditions.

Accepted Answer

A)  internal
B)  protein
C)  environmental
D)  genetic

Question 2

Histones that are tightly wound by DNA and are the basic unit of chromatin are called

Accepted Answer

A)  operons.
B)  nucleosomes.
C)  protein clusters.
D)  repressor genes.

Question 3

Vertebrate cells possess a protein that binds to clusters of 5-methylcytosine and ensures the gene will stay in the "off" position.This control of gene regulation is a result of

Accepted Answer

A)  translation.
B)  enhancer expression.
C)  methylation.
D)  promoter expression.

Question 4

You are studying the effects of specific transcription factors on the activation of gene expression.You notice that one particular transcription factor binds far away from the promoter of its target gene.What can explain this?

Accepted Answer

A)  The transcription factor transcribes small RNAs that then bind to the promoter and activate the gene's expression.
B)  The transcription factor tags the enhancer with ubiquitin to stimulate transcription.
C)  DNA looping brings the transcription factor closer to the promoter and initiates gene transcription.
D)  RNA looping brings the transcription factor closer to the promoter and initiates gene transcription.

Question 5

The enzyme dicer chops dsRNA molecules into small pieces of

Accepted Answer

A)  mRNA and miRNA.
B)  miRNA and siRNA.
C)  siRNA and rRNA.
D)  mRNA and siRNA.

Question 6

A cluster of functionally-related genes that are regulated together and encoded into a single mRNA molecule is called a(n)

Accepted Answer

A)  operon.
B)  repressor.
C)  promoter.
D)  operator.
