What is an example of a post transcriptional regulation?Keep it short and simple

What is a TATA box? Where is it located? What is a promoter? Where is it located in comparison with the gene it will regulate?

Describe 2 different general ways that a transcriptional regulation protein works. In other ways, what are the 2 flavors of transcriptional regulation

In a bacterium, most expression regulation occurs because of the strength of a gene’s promoter.  What does this refer to?  Make sure you describe how two constitutively expressed genes can have lots/little transcription occurring.

Blood taken from Raymond is injected into Fred, causing increased transcription of red protein in Fred's cells You take a sample of Raymond's blood, mix it with a 50-50 mix of water and oil. Injecting the water fraction into Fred has no effect, while injecting the oil fraction causes increased transcription of red protein in Fred's cells. The chemical agent causing these effects in Fred is most probably O #3 A sterold hormone O #1 Acting via CAMP O #2 Binding to a plasma membrane-bound receptor on Fred's cells O #1 and #2 O #1, #2 and #3

Gene B has a mutation in its promoter sequences changing TATA to GAGA. What will this mean for transcription and why?
