Question

Which among the following statements are true regarding the chromatin material?

• A. Supercoiled DNA structures are made up of the chromatin fibre.
• B. The DNA coils itself to form lumps
• C. The DNA along with 8 histone proteins form the nucleosome
• D. The chromatin fibres are packed inside the nucleosomes

Answer 1

Answer: (A), (C)

The correct options are
A

Supercoiled DNA structures are made up of the chromatin fibre.

C

The DNA along with 8 histone proteins form the nucleosome

Chromosomes are found inside the nucleus of a cell.

The chromatin fibre is formed by a combination of 40% DNA and 60% of histones.

The histone proteins help in the condensation of DNA and packing it into structures called the chromatin fibres.

The DNA molecules wind themselves around a core of 8 histone proteins to form nucleosomes that are further condensed to form the chromatin material.
