Glycolysis breaks the glucose molecule into two pyruvate molecules, and they still have high energy bonds. These bond are broken during the aerobic respiration part and the energy released from them is stored in the ATP molecules which will then be used by the cell as an energy source.
Answer:
Option-B
Explanation:
DNase I is an enzyme which acts on the DNA in its single-stranded, double-stranded and chromatin form.
The DNase acting sites on the DNA is known as the DNA I hypersensitive site. The DNase I hypersensitive site allows the DNase I to act as the condensed form becomes less condensed. This mechanism can be associated with the transcription as, during transcription, the DNA becomes less condensed and is open to DNase I enzyme.
Thus, Option-B is correct.

Prokaryotes
↬ No well defined nucleus.
↬ DNA is held with some proteins in nucleoid region.
Eukaryotes
↬ <u>Histones</u>:
- ↬ Positively charged proteins.
- ↬ Rich in arginine and lysine.
- ↬ 5 types:- H₁ H₂A, H₂B, H₃ H₄.
↬ <u>Histone octamer</u>:
↬ <u>Nucleosome</u>:
- ↬ DNA (-ve charge) makes two complete turns around the histone octamer (+ve charge) to form a nucleosome.
