MCQ
Nucleosome core is made of:
  • A

    $\text{H}_1, \text{H}_2\text{A}, \text{H}_2\text{B and H}_3.$

  • B

    $\text{H}_1, \text{H}_2\text{A}, \text{H}_2\text{B}, \text{H}_4.$

  • C

    $\text{H}_1,\text{H}_2\text{A}, \text{H}_2\text{B}, \text{H}_3 \text{ and H}_4.$

  • D

    $\text{H}_2\text{A}, \text{H}_2\text{B}, \text{H}_3 \text{ and H}_4.$

Answer

  1. ​​​​​$\text{H}_2\text{A}, \text{H}_2\text{B}, \text{H}_3 \text{ and H}_4.$

Explanation:

Nucleosome core or histone octamer is made up 2 sub units each of $\text{H}_2\text{A}, \text{H}_2\text{B}, \text{H}_3,\text{H}_4.$ Two cores are linked by the linker DNA containing histone H1 molecule.
