Summary

Organisms use the process of transcription to make mRNA as a temporary molecule to transport protein coding information from a gene. The translation process reads the mRNA and makes the intended protein, one amino acid at a time. This process is controlled by the promoter of the gene to insure that proteins are made in the right cells at the right time to drive growth, development, metabolism, stress response and other processes needed to complete the organisms life cycle. The next lesson (Gene expression part 2) will apply the gene expression principles to the observation that some plants can be resistant to ALS inhibitor herbicides.
