The association of histone H1 with a nucleosome indicates:

1. DNA replication is occurring

2. The DNA is condensed into a chromatin fibre

3. The DNA double helix is exposed

4. Transcription is occurring

Which one of the following statements about Histones is wrong?

1.	Histones are rich in amino acids - Lysine and Arginine.
2.	Histones carry a positive charge in the side chain.
3.	Histones are organized to form a unit of 8 molecules
4.	Histones are organized to form a unit of 10 molecules

Given below are two statements:

Statement I:	In prokaryotes, the positively charged DNA is held with some negatively charged proteins in a region called nucleoid.
Statement II:	In eukaryotes, the negatively charged DNA is wrapped around the positively charged histone octamer to form nucleosome.

In the light of the above statements, choose the correct answer from the options given below:
1. Statement I is incorrect but Statement II is correct.
2. Both Statement I and Statement II are correct.
3. Both Statement I and Statement II are incorrect.
4. Statement I is correct but Statement II is incorrect.

Histones are enriched with
1. Phenylalanine & Leucine
2. Phenylalanine & Arginine
3. Lysine & Arginine
4. Leucine & Lysine
