1 What is the primary function of DNA polymerase during DNA replication?
Correct Answer:
D
Explanation: DNA polymerase is the enzyme responsible for synthesizing new DNA strands by adding nucleotides complementary to the template strand during DNA replication.

2 During which phase of mitosis do sister chromatids separate and move to opposite poles of the cell?
Correct Answer:
A
Explanation: Sister chromatids separate during anaphase, which is the stage in mitosis where they are pulled apart to opposite sides of the dividing cell.

3 Which type of mutation involves a change in a single nucleotide base pair?
Correct Answer:
C
Explanation: A point mutation is a change in a single nucleotide base pair, which can lead to changes in the amino acid sequence of a protein.

4 What is the process by which messenger RNA is synthesized from a DNA template called?
Correct Answer:
A
Explanation: Transcription is the process by which messenger RNA (mRNA) is synthesized from a DNA template, allowing the genetic information to be converted into a format that can be translated into proteins.

5 In meiosis, what is the significance of crossing over?
Correct Answer:
C
Explanation: Crossing over is a process that occurs during meiosis where homologous chromosomes exchange genetic material, leading to increased genetic variation among the resulting gametes.
