Transcription

Transcription is process wherein _____ is used as a template to produce ______.

• Protein; RNA

• DNA; protein

• DNA; RNA

• RNA; DNA

• Protein; DNA

Where does transcription occur within a eukaryotic cell?

• Smooth ER

• Ribosome

• Rough ER

• Nucleus

• Cytosol/cytoplasm

What is the role (or job) of RNA polymerase?

• unzip the DNA helix

• copy the DNA

• create the sequence of nucleotides that will become the mRNA

• twist the DNA

Transcription begins at a region within the DNA known as a(n) ____________, and mRNA is synthesized in the ______________.

• Start codon; 3' --> 5' direction

• Start codon; 5' --> 3' direction

• Origin of Transcription; 3' --> 5' direction

• Promoter; 5' --> 3' direction

• Promoter; 3' --> 5' direction

Unlike in DNA replication which requires SSBPs, DNA Polymerase, Helicase, and Topoisomerase, in the process of transcription only RNA Polymerase is needed to both unzip the DNA and transcribe it.

• True

• False

• 3' - ATG ATC TCG TAA - 5'

• 5' - ATG ATC TCG TAA - 3'

• 3' - AUG AUC UCG UAA - 5'
