Solution
The correct option is B GCTACCGAT
The nitrogen bases for DNA are thymine (T), guanine (G), cytosine (C) and adenine(A) and for RNA they are adenine, guanine, cytosine and uracil (U). G pairs with C and U pairs with A during transcription. Transcription is the system that produces a complementary RNA sequence from a strand of DNA. This enzyme, which naturally occurs in retroviruses, operates on a single strand of mRNA, generating its complementary DNA based on the pairing of RNA base pairs (A, T, G and C) to their DNA complements (T, A, C and G), respectively. Hence the complimentary strand for this segment is GCTACCGAT.So, the correct answer is option B.
