Document Summary
Before, we primarily took a look at prokaryotes, this lecture starts us off on eukaryotes. trna base pairs with itself, dna, and other rna during synthesis and function. All rna pairs with dna when it is being synthesized. Even if there is lactose around, repressor binds a little bit just not as much. The rate of transcription is higher, but that doesn"t mean the repressor still doesn"t bind to it. microrna are regulatory rna. Their job is to affect translation of other rna. It is an rna, so it pairs with itself and all that stuff. But after it gets process microrna complementary base pairs with another mrna on the 3" utr and it prevents translation. This is known as anti- sense. microrna is antisense to the mrna. Double stranded rna (microrna and mrna) can"t be translated. Identify the various signals coded in dna in eukaryotic genes (noting which are different from prokaryotes).
