One strand of a `DNA` has the sequence `ATGCTTCA`. What is the sequence of the bases in the complementary strand?

Text Solution

Verified by Experts

We know that in `DNA` molecule, adenine `(A)` always pairs with thymine `(T)` and cyosine `(C )` always pairs with gunine `(G)`. Thus,
sequence of bases in one strand:
`A T G C T T C A`
`:.` Sequence of bases in the complementary strand:
`T A C G A A G T`
Thus, the sequence of bases in the complementary strand is `TACGA AGT`.
