Session Overview

Molecbio_sess3.jpg

This session will explain how the cell uses its DNA instructions to make a RNA message, and the RNA message to make a protein.

Learning Objectives

  • Outline the processes of transcription and translation.
  • List the basic components needed to successfully undergo transcription and translation.
  • Understand the purpose of the cell’s performing transcription and translation.
  • Predict RNA and protein sequences from a given gene.
  • Analyze the effects of a DNA mutation on the RNA and protein produced from that DNA.
