Question

Does the mRNA model more closely resemble the DNA strand from which it was transcribed?

Answer 1

mRNA more closely resembles the strand of DNA that was not transcribed.
This is because bases in DNA always make one of two pairs,either C-G or A-T.So a strand of DNA coded ATCG would have a complementary strand of TAGC.
RNA bonds to DNA in the same manner,except instead of T,it uses U.So,the DNA strand mentioned earlier,ATCG,would be transcribed into UAGC.

Answer 2

The mRNA model does not closely resemble the DNA strand from where it was transcribed.

• mRNA is a single-stranded molecule whereas DNA is a double-stranded molecule. mRNA is synthesized from DNA through the process of transcription.

• RNA polymerase is an enzyme that helps in the transcription of the mRNA. This reads the sequence of the DNA to form an mRNA. They form complementary strands.

• The mRNA and DNA model is not the same since mRNA is single-stranded and DNA is a double-stranded helical molecule, Both DNA and mRNA are sequenced with Nitrogenous base pairs. But if DNA has thymine then the mRNA will code for uracil.
• The DNA will code for genetic information and the mRNA will code for the proteins that are supposed to be processed.
