|
Eukaryotes use RNA Polymerase I, II, and III. What do each create? |
I- rRNA II- mRNA III- tRNA II and III- snRNA |
|
|
CAAT and GC-rich areas are examples of what? What is their interaction with activators? |
Promoter-proximal regions. They attract activator proteins, making transcription more efficient. |
|
|
What is the location, full sequence, and function of the Goldberg-Hogness box? |
Is as -30 on many genes in eukaryotes. TATAAA. Allows GTF TFIID a place to bind in eukaryotes. A.k.a. the Goldberg-Hogness box. |
|
|
What is the transcription initiation complex? When does it form and in what type of organism (prokes or euks)? Why does it form in that type of organism? |
It forms when the GTF TFIID binds to the TATA box of a gene's promoter. This only occurs n eukaryotes because euk RNA Poly cannot bind directly to DNA. |
|
|
What are the two terminuses of a polypeptide chain? Which is the beginning, which is the end? |
N- and carboxyl-terminus. N- is taken to be the beginning. |
|
|
What are the two classes of regulatory proteins? |
Activators and repressors. |
|
|
What is the location, full sequence, and function of the Pribnow box? |
-10 on many genes in prokaryotes. TATAAT. Acts as an necessary part of the gene's promoter. |
