Bingel [31]

Compare and contrast the structures of DNA and RNA
katovenus [111]

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. The only difference between ribose and deoxyribose is that ribose has one more -OH group than deoxyribose, which has -H attached to the second (2') carbon in the ring. DNA is a double-stranded molecule, while RNA is a single-stranded molecule.

Proteins around which the long, linear strands of DNA are wrapped; they serve to keep the DNA untangled and to enable an orderly
igor_vitrenko [27]

Answer:

The correct answer is- Histone

Explanation:

DNA is approximately 2.2 m long thread which has to be adjusted in a microscopic nucleus so DNA must be in a supercoiled form to be present in the nucleus and this supercoiling of DNA is done on histone protein.

Histone protein is a positively charged protein that is made up of eight proteins so it is called histone octamer. Each histone has 2 copies of each protein that is H2A, H2B, H3, and H4.

DNA is negatively charged and histone protein is positively charged therefore DNA wraps around histone protein which causes the packaging of DNA. So the correct answer is histone protein.
