Question 3

After reading the paragraph below, answer the question that follows.
Mitochondria contain their own small genome that contains information to make ribosomal RNAs, transfer RNAs, and a few proteins. Interestingly, the mitochondrial genome has a different genetic code than nuclear DNA. Occasionally, mitochondrial DNA escapes the mitochondrial compartment and enters the cytosol and nucleus.

Accepted Answer

A)  It could be transcribed and translated into functional proteins. 
B)  It could be transcribed and translated into nonfunctional proteins. 
C)  It could be transcribed but not translated. 
D)  It could not be transcribed. 
A)  It could be transcribed and translated into functional proteins. 
B)  It could be transcribed and translated into nonfunctional proteins. 
C)  It could be transcribed but not translated. 
D)  It could not be transcribed. B

D)  dipole-dipole bonds 
A)  hydrogen bonds 
B)  covalent bonds 
C)  noncovalent bonds

Question 5

Approximately what percentage of the human genome is identical to that of a chimpanzee?

Accepted Answer

A)  50.0% 
B)  62.3% 
C)  92.0% 
D)  98.8% 
A)  50.0% 
B)  62.3% 
C)  92.0%

Question 6

After reading the paragraph below, answer the question that follows.
Gene therapy is a relatively new approach to treating inherited disorders. In effect, a good, working copy of the affected gene is introduced into multiple cells on an expression vector (typically a virus). The good gene is incorporated into the genome of each cell, thus providing the information missing due to the host cell's mutated gene.
-Which of the following statements regarding gene therapy is incorrect?

Accepted Answer

A)  Successful infection of the good gene into tissue resident stem cells will promote the gradual replacement of 'bad' cells with 'good' ones, i.e. those that have a good copy of the gene. 
B)  Successful infection of the good gene into post-mitotic tissue cells will require that a great many individual cells take up and incorporate the good gene. 
C)  Once the good gene is incorporated into a cell's genome, there is effectively no mechanism to remove it. 
D)  A 'bad' gene product can still overcome the benefit of the 'good' gene and this is called a dominant negative effect.
