Question

during elongation, how does the forming mrna strand compare to the dna strands? complete the paragraph. the mrna strand has a sequence of nitrogenous bases complementary to that of the ____ strand and identical to that of the __ strand, except it contains uracil instead of ____. coding...template...adenine template...coding...thymine coding...template...thymine template...coding...adenine

Explanation:

During transcription elongation, mRNA is synthesized using the DNA template strand as a guide, so its bases are complementary to the template strand. The DNA coding (sense) strand has the same base sequence as the mRNA, with the only difference being that mRNA uses uracil (U) instead of the thymine (T) found in the coding strand.

Answer:

template...coding...thymine
