| (i) Nucleosome contains basic protein. |
| (ii) Tightly packed DNA of chromatin is called heterochromatin. |
| (iii) Loosely packed DNA of chromatin is called euchromatin. |
| (iv) \[{{H}_{2}}A,{{H}_{2}}B\] are linker proteins. |
| (v) DNA is basic in nature. |
A) (i),(ii) and (iii),
B) (i) and (ii)
C) (i), (ii), (iii), (iv) and (v)
D) (iv) and (v)
Correct Answer: A
Solution :
[a] \[{{H}_{2}}A,\,{{H}_{2}}B,\,{{H}_{3}}\,and\,{{H}_{4}}\] are called the core histone proteins, H , is called the linker histone protein because it joins the two histone octamers. DNA is acidic in nature.
