| Observe the diagram given below of a nucleosome model and answer the following questions. |
 |
| (i) The number of nucleosomes present in human cell is |
A) \[3.3\times {{10}^{7}}\] nucleosome
B) \[1.1\times {{10}^{7}}\] nucleosome
C) \[6.6\times {{10}^{7}}\] nucleosome
D) Indefinite
Correct Answer: A
Solution :
[a] Approximately 200 bp are present per nucleosome. Total number of base pairs in human's genetic material is \[=6.6\times {{10}^{9}}\]. Number of nucleosomes \[\frac{6.6\times {{10}^{9}}}{200}=3.3\times {{10}^{7}}\]
