The antiparallel strands in $DNA$ are the result of:

If the base sequence of one strand of $DNA$ is $GAT, TAG, CAT, GAC$,what would be the sequence of its complementary strand?

Who proposed that for a double-stranded $\text{DNA},$ the ratios between Adenine and Thymine and Guanine and Cytosine are constant and equal to one?

Who amongst the following scientists had no contribution in the development of the double-helix model for the structure of $DNA$?

Match the following columns $:-$

Column-$I$	Column-$II$
$(a)$ $\phi \times 174$ bacteriophage	$(i)$ $48502 \ \text{b.p}$
$(b)$ Human (diploid)	$(ii)$ $5386$ bases
$(c)$ $E. coli$	$(iii)$ $6.6 \times 10^9 \ \text{b.p}$
$(d)$ $\lambda$-phage	$(iv)$ $4.6 \times 10^6 \ \text{b.p}$

If the sequence of bases in one of the $DNA$ strand is $A, G, G, A, G, A, A$,then the sequence of bases in the other complementary strand of $DNA$ would be
