DOES THE mRNA MODEL MORE CLOSELY RESEMBLE THE DNA STRAND FROM WHICH IT BWAS TRANSCRIBED?

Yes, the mRNA model closely resembles the DNA strand from which it was transcribed, specifically the coding or sense strand. The mRNA sequence is complementary to the DNA template strand and contains uracil (U) instead of thymine (T). However, while they share similar sequences, mRNA is typically single-stranded and undergoes modifications like splicing, capping, and polyadenylation, which differentiate it from the original DNA strand.
