Bio 191 LEC 1st Exam Questions
and Correct Answers

In which direction is the DNA template read during DNA replication?

✓✓~ 3' to 5'




Which of the following is not a structural property of DNA?

✓✓~ Single stranded




If DNA polymerase was nonfunctional in a cell what would happen regarding DNA

replication?

✓✓~ New nucleotides would not be added in a 5' to 3' direction




Which of the following is true regarding DNA replication?

✓✓~ It occurs in both directions at the same time




Which component of a nucleotide is involved in complementary base pairing?

✓✓~ Nitrogenous base




Describe at least four structural features of DNA

✓✓~ Double Helix Structure, Base Pairs, Antiparallel Strands, Major and Minor Grooves.

, What are the three components of a nucleotide?

✓✓~ Phosphate Group, Sugar Molecule, Nitrogenous Base:

Adenine (A): Found in both DNA and RNA.

Thymine (T): Found exclusively in DNA.

Cytosine (C): Found in both DNA and RNA.

Guanine (G): Found in both DNA and RNA.




Identify which nucleotides bind together (Watson-Crick binding) and state hydrogen

bonds form between each pairing

✓✓~ A, T: 2 hydrogen bonds form between adenine (A) and thymine (T). These hydrogen bonds
help hold the two DNA strands together.
C, G: 3 hydrogen bonds form between cytosine (C) and guanine (G). This results in

a stronger bond compared to the A-T pair, which has two hydrogen bonds.




Explain how DNA becomes a polynucleotide chain.

✓✓~ DNA is made of four types of nucleotides, which are linked covalently into a polynucleotide
chain (a DNA strand) with a sugar-phosphate backbone from which the bases (A, C, G, and T)
extend.




Explain what the term complementary means in terms of DNA.

✓✓~ Complementary base pairing describes in which the nitrogenous bases of the DNA
molecules align with each other. Complementary base pairings are also responsible for the
double-helix structure of DNA.
