Thymine is

In $DNA$,the linkages between different nitrogenous bases are

$DNA$ multiplication is called:

In the $DNA$ of $E. coli$,the mole ratio of adenine to cytosine is $0.7$. If the number of moles of adenine in the $DNA$ is $350000$,the number of moles of guanine is equal to:

Given below are two statements:
Statement $I$: Cytosine and guanine are formed in equal quantities in $DNA$ hydrolysis.
Statement $II$: Adenine and uracil are formed in equal quantities in $RNA$ hydrolysis.
The correct answer is:

An example of a natural biopolymer is........
