The genetically active area of a chromosome is called:

If a double-stranded $DNA$ has $35 \%$ Guanine,calculate the percent of Thymine in the $DNA$. (in $\%$)

If a double stranded $DNA$ has $20$ percent of cytosine,calculate the percent of adenine in the $DNA$. (in $\%$)

The base sequence for a nucleic acid segment is given as $CAG, AGG, CGA, CCA$. From this,it can definitely be concluded that it is a segment of:

$A$ gene is made up of

Which structure contains the coded information required to produce the chemicals necessary for performing parental functions?
