Concept #1: Prokaryotic Gene Expression

Practice: Which of the following statements is true?

Concept #2: Prokaryotic Gene Expression

Practice: PRACTICE: In prokaryotes, as soon as RNA polymerase synthesizes the 5' end of mRNA, ribosomes come in and initiate translation before transcription is completed. This is called ____.
