The segment of $DNA$ which acts as the instrumental manual for the synthesis of the protein is

The primary structure of a nucleic acid contains the base sequence $GATGC...$. Which of the following chains is complementary to this sequence?

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:

Which of the following bases are present in both $DNA$ and $RNA$?

What products would be formed when a nucleotide from $DNA$ containing thymine is hydrolysed?

The reason for the double helical structure of $DNA$ is the operation of
