The figure below represents the structure of the chromosome. Select the correct option regarding the structure.

Options

  1. A1 - Centromere, 2 - Chromatid, and the number of chromosome is 1
  2. B1 - Centromere, 2 - Telomere, and the number of chromosome is 2
  3. C1 - Chromatid, 2 - Telomere, and the number of chromosome is 1
  4. D1 - Telomere, 2 - Chromatid and the number of chromosome is 2

Correct answer

B. 1 - Centromere, 2 - Telomere, and the number of chromosome is 2

Step-by-step solution

Centromere is the primary constriction found in chromosome of dividing cells. Centromere holds the two sister chromatids together. Each chromatid generally have 2 DNA; thus, a chromosome of 2 sister chromatids will have 4 DNA. Telomere is the end or the terminal region of a chromosome.
