Question 1

Would you expect the presence of spacer DNA to increase or decrease the frequency of linkage between genes?

Accepted Answer

A)  Decrease it, because the spacer DNA is removed from the genome before transcription. 
B)  Decrease it, because the spacer DNA increases the probability of crossing-over between genes. 
C)  Increase it, because the spacer DNA is tightly connected to the genes on both sides. 
D)  Increase it, because the spacer DNA encourages the insertion of transposons into the DNA.

C)  Increase it, because the spacer DNA is tightly connected to the genes on both sides. 
D)  Increase it, because the spacer DNA encourages the insertion of transposons into the DNA.

Question 2

The early hypothesis that protein was the genetic material was based in part on the

Accepted Answer

A)  knowledge that chromosomes were composed of protein. 
B)  fact that proteins are small molecules and therefore easily copied. 
C)  fact that protein molecules are large and could carry a lot of information. 
D)  the idea that DNA molecules varied too much within cells of the same organism.
