15. Which step begins the process of transcription?

A. The mRNA template enters the cytoplasm
B. RNA polymerase opens the double helix of DNA
C. The tRNA molecule binds to the "start" codon on the mRNA strand
D. The tRNA molecule recognizes the mRNA codon through its anticodon



Answer :

Final answer:

Transcription initiates with RNA polymerase opening the DNA double helix to create mRNA, followed by further processing in the nucleus and translation in the cytoplasm.


Explanation:

Transcription is the process where RNA polymerase opens the double helix of DNA to begin synthesis of mRNA using the DNA strand as a template. The mRNA is then processed further in the nucleus and leaves to the cytoplasm for translation.

Ribonucleotides bond with the exposed deoxyribonucleotides during transcription through complementary base pairing, and the RNA polymerase continues until it encounters a stop signal.

Gene transcription converts DNA into RNA by RNA polymerase unwinding the DNA, creating mRNA that carries the genetic information for protein synthesis.
