Question

name and describe the process occurring in the nucleus wich results in the formation of an mRNA molecule.​

Answer 1

Answer:

The correct answer is - transcription.

Explanation:

Transcription is the process that takes place in the nucleus and the final result of the process is an mRNA molecule that encodes the information of a specific DNA sequence.

Transcription in prokaryotes is carried out in three stages.  

Initiation: Here, RNA polymerase binds to the promoter region and transiently binds to the ‘initiation factor’ to initiate transcription.

Elongation: This is the step where the RNA strand starts getting longer. RNA polymerase “walks” along one strand of DNA. For every nucleotide recognized on the DNA template, it adds a complementary RNA nucleotide to the growing RNA transcript.

Termination: Transcription stops once the RNA polymerase reaches the terminator region. At this region, the RNA transcript and the RNA polymerase, both fall off. RNA polymerase transiently associates with the ‘termination factor’ to stop transcription.
