THE lac OPERON
, The control of gene expression
• Each cell in the human contains all the genetic
material for the growth and development of a
human
• Some of these genes will be need to be expressed all
the time
• These are the genes that are involved in of vital
biochemical processes such as respiration
• Other genes are not expressed all the time
• They are switched on an off at need
, Operons
• An operon is a group of
genes that are
transcribed at the
same time.
• They usually control an
important biochemical
process. Jacob, Monod & Lwoff
• They are only found in © NobelPrize.org
prokaryotes.
