Question

During analysis of the $DNA$ of an organism having $5386$ nucleotides find out $A=29\text{\%},G=17\text{\%},C=32\text{\%},T=17\text{\%}$. Considering the Chargaff’s rule, it can be concluded that:

• A. It is double-stranded linear $DNA$
• B. It is double-stranded circular $DNA$
• C. It is single-stranded $DNA$
• D. Both a and b

Answer 1

The correct option is C It is single-stranded $DNA$

If there are $5386$ nucleotides and $A=29\text{\%},G=17\text{\%},C=32\text{\%}$ and $T=17\text{\%}$, then considering the Chargaff’s rule, it can be concluded that it is a single-stranded $DNA$ as the ratio of adenine and thymine is not equal to the amount of guanine and cytosine.
