Overview of transcription |
-RNA polymerase one DNA dependent - ignition, elongation, termination |
|
|
2 ways of terminating transcription |
Rho protein, rho protein removes polymerase from the DNA strand AND hair pen loop |
|
|
Hair pen loop |
Inverted repeats on the DNA strand followed by poly AAA, causes the mRNA strand to form a stem loop in RNA immediately upstream from a run of UUU |
|
|
Hair pen loop |
Inverted repeats on the DNA strand followed by poly AAA, causes the mRNA strand to form a stem loop in RNA immediately upstream from a run of UUU |
|
|
Topoisomerases (gyrases) |
Functions to uncoil super coiled DNA domains, using t1 top. Upstream from replication forks and top. 11 to recoil newly produced DNA stands after replication fork moves on. |
