Assertion : Histones are basic proteins ...

Assertion : Histones are basic proteins of major importance in packaging of eukaryotic DNA, DNA and histones comprise chromatin forming the bulk of eukaryotic chromosome .
Reason : Histones are five major types `H_(1), H_(2)A, H_(2)B, H_(30` and `H_(4)`

A

If both the assertion and the reason are true and the reason is a correct explanation of the assertion

B

If both the assertion and reason are true but the reason is not a correct explanation of the assertion

C

If the assertion is true but the reason is false

D

If both the assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
B
There are five major types of histones proteins such as `H_(1)` , H2A , H2B , H3 and H4 arranged in the form of histone octamers.
Histones are the basic proteins made up of positively charged amino acids such as lysine and argine. DNA being negatively charged bind to positively charge of histone protein to form nucleosome

Assertion. Histones are basic protein of major importance in packaging of eukaryotic DNA. DNA and histone comprise chromatin forming bulk of eukaryotic chromosome. Reason. Histones are five major types H_(1), H_(2)A, H_(2)B, H_(3) and H_(4) .

Assertion :- Positively charged histone proteins are essential for packaging negatively charged DNA. Reason : Without histone protein DNA can not fold due to negative charge.

Assertion : Histone proteins are synthesized during the S-phase when DNA synthesis occurs. Reason : Histone proteins form an association with DNA to form nucleosome.

Assertion: Histone proteins are synthesised during S-phase. Reason: Histone proteins are found associate with DNA to form bead-like nucleosomes.

Assertion : DNA is associated with proteins. Reason : DNA binds around histone proteins that form a pool and the entire structure is called a nucleosome.
