Genome $= ......$

Assertion $(S)$: $RNA$ does not contain $T$ (Thymine).
Reason $(R)$: $DNA$ does not contain $U$ (Uracil).

In a given $DNA$ segment,the number of nucleotides of guanine is $75$ and those of thymine is $75$. The total number of nucleotides in the segment will be:

If the $DNA$ of $E. coli$ is $1.36 \ mm$ long,how many base pairs $(bp)$ does it contain?

If a $DNA$ molecule contains $10,000$ base pairs, how many nucleotides does it have?
