Question

1. In a few sentences that are your own, describe the process of transcription. Be sure to explain where it occurs in the eukaryotic cell, how it starts, what the enzyme does, and how it ends. Be sure to include these terms in your description: RNA polymerase, template strand, promoter, RNA nucleotides, terminator, and pre-RNA transcript.

Answer 1

Explanation:transcription is the transfer of genetic information from DNA to mRNA, which can be translated to a functional protein. Eukaryotic transcription occurs in the nucleus. The process starts when RNA polymerase regonises certain transcription factors upstream of the promoter region. binding of RNA polymerase to these transcription factors in addition to other molecules form the basal transcription factor. The enzyme then moves from 5' to 3' of the template strand (strand to be transcribed) adding corresponding nucleotides to form the new RNA strand (pre mRNA). The newly synthesized RNA then undergoes three basic steps ( capping, polyadenylation and splicing) to become a mature translatable mRNA.
