Question 1

Why do scientists believe that most of the unexplored genetic diversity on Earth resides in viral genomes? Why is this genetic diversity important to human society?

Accepted Answer

First,there are ten times as many virus

Question 2

You isolate a purify a bacteriophage that can replicate in E.coli.Through chemical analyses you determine that the only nucleic acid present is RNA.You isolate the RNA and put it in a test tube with all of the necessary proteins and RNAs for translation.The RNA is translated and new infectious virions are made.What does this tell you about the bacteriophage?

Accepted Answer

A)  The RNA genome is of the plus sense. 
B)  The RNA genome is of the plus sense and RNA replicase is present in the viral capsid. 
C)  The new bacteriophage is a retrovirus. 
D)  RNA replicase is present in the viral capsid. 
A)  The RNA genome is of the plus sense. 
B)  The RNA genome is of the plus sense and RNA replicase is present in the viral capsid. 
C)  The new bacteriophage is a retrovirus. 
D)  RNA replicase is present in the viral capsid.

Question 3

When packaged in the virion,the complete complex of nucleic acid and protein is known as the virus

Accepted Answer

A)  capsid. 
B)  concatemer. 
C)  nucleocapsid. 
D)  envelope. 
A)  capsid. 
B)  concatemer. 
C)  nucleocapsid. 
D)  envelope.

Question 4

What would be the consequence of deleting the late T4 genes?

Accepted Answer

A)  The T4 genome would not be copied. 
B)  T4 mRNA would not be produced. 
C)  T4 capsid proteins would not be made. 
D)  ATP would not be produced and the T4 genome would not be packaged into the capsid. 
A)  The T4 genome would not be copied. 
B)  T4 mRNA would not be produced. 
C)  T4 capsid proteins would not be made. 
D)  ATP would not be produced and the T4 genome would not be packaged into the capsid.

Question 5

Which of the following samples would contain the MOST genetic diversity?

Accepted Answer

A)  viral metagenomes from the ocean 
B)  bacterial metagenomes from the ocean 
C)  microbial eukaryotic metagenomes from the ocean 
D)  viral metagenomes from human red blood cells 
A)  viral metagenomes from the ocean
