Worksheet 12
Oregon State University
Dr. Richard Nafshun
1.
What are two products of the citric acid cycle?
2.
Describe the structure of DNA.
3.
Between the two DNA strands (in an intact double helix), A bonds with ____, and C
bonds with _____. This is due to ___________________ bonding. A and T form
______ hydrogen bonds, C and G form ______ hydrogen bonds. This "lock-and-key"
model is due to hydrogen bonding and __________.
4.
Why is dATP one of the four precursors of DNA, but dAMP is not?
5.
The synthesis of new DNA from the direction of the original DNA is termed:
(A)
(B)
(C)
(D)
(E)
6.
Replication.
Copy.
Xerox.
Mutation.
Doubling.
The human genome consists of approximately 5 x 109 base pairs (each is 0.34 nm).
Therefore, the length of DNA in each cell is:
(A)
(B)
(C)
(D)
(E)
1.7 nm long.
1.7 miles long.
1.7 m long.
About 0.34 nm long.
from here to Eugene. Get it? Eu-Gene?
7.
How does DNA differ from RNA?
8.
There are four major types of RNA. Give their function.
9.
The nucleotide sequence of DNA was found to be 5'-G-G-A-T-A-3'. The transcript
strand of RNA is _______________.
