Red Blood Cells are approximately 0.01 mm, so only one can pass through the small capillary. The advantage of this is that there is a larger surface area exposed, more time available and shorter difference for exchange of oxygen.
RNA polymerase binds to the lac promoter and begins transcribing
the stretch of DNA to messenger RNA.
Therefore, in other words, the stretch of DNA is expressed. The DNA sequence of
the lac promoter 'signals' where the RNA
polymerase will bind and where transcription
will begin. Promoters are found upstream of a gene to be transcribed.
