Prokaryotic Transcription

Chp 15

Multiple Choice

If the DNA sequence says TAC CGA TCT what will the mRNA transcript read?

• ATG GCU AGA

• AUG GCU AGA

• AGA UCG GTA

Multiple Choice

RNA Polymerase can only transcribe DNA in the _____ direction.

• 3' to 5'

• 5' to 3'

Multiple Choice

In transcription, the nucleotides will be added on the ___ end of the molecule via RNA Polymerase
