Suppose that, on another planet, life had evolved with double-stranded DNA containing four pairs of complementary bases for example, A-T, G-C, U-V, and W-X, instead of Earthly DNA with only two pairs, A-T and G-C. Compared with shotgun sequencing of Earthly DNA with two base pairs, would genome assembly be easier or harder on this other planet where DNA contains four base pairs? Why?

a. DNA with four base pairs would be easier to assemble because DNA with two base pairs has more repeated sequences,
b. DNA with four base pairs would be harder to assemble because DNA with two base pairs has fewer repeated sequences.
c. DNA with four base pairs would be easier to assemble because DNA with two base pairs requires longer overlaps to find matches.
d. DNA with four base pairs would be harder to assemble because DNA with two base pairs requires shorter overlaps to find matches.
e. None of the other answer options is correct.
