Worked practice questions

Aligned bases on one DNA strand are A-T-G-C. Which bases face them, in that order?

  1. T-A-C-G
  2. G-C-A-T
  3. A-T-G-C
  4. C-G-T-A
Show answer and solution

Correct answer: A. T-A-C-G

Applying A-T and G-C pairing to the four positions gives T-A-C-G.

Within a human nuclear chromosome, a gene is best described as

  1. the entire centromere alone
  2. a particular segment of DNA
  3. a complete chromosome set
  4. a complete homologous pair
Show answer and solution

Correct answer: B. a particular segment of DNA

A gene occupies a particular DNA sequence within a chromosome.

Which chromosome region appears as a constriction?

  1. The centromere region
  2. The chromosome arms
  3. The nucleosome core
  4. The DNA double helix
Show answer and solution

Correct answer: A. The centromere region

The centromere is a constricted region of the chromosome.
