The recruitment and transcription initiation of RNA pol III on all three types of promoters use
TFIIIB
What must occur for elongation to begin by RNA pol III that is bound to an internal promoter?
Transcription factors that are bound downstream from the transcription start site must be removed
What are the three distinct activities of protein synthesis?
Initiation, elongation and termination
What enzyme is responsible for covalently linking amino acids to the three end of the cognate tRNA?
Amino acyl tRNA synthetase
What is the name of the nucleotide sequence that helps the 30 S ribosomal sub unit find the initiation codon on the bacterial mRNAs
The shine dalgarno sequence
Which is always the first amino acid Incorporated at the n terminus
Methionine
The initiator tRNA enters the 30 S ribosomal subunit at the
P site
Promoter for tRNA genes
Internal promoter A-B box
Hershey and Chase
Used T2 to see wether DNA or protein was the genetic material
Chargaffs rule
The amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine
Mendels Law
Includes three principles, dominance segregation, and independent assortment
The wobble hypothesis by Watson
First two bases of the codon have precise pairing with the bases of the anticodon while pairing between the third bases
Three events in eukaryotic mRNA
Five capping, splicing, three polyadenylation
What is the function of the CTD of RNA pol II
Phosphorylation regulates the recruitment of protein factors that influence transcription
Lacl
Active in the Freeform and inactive when complex with inducer
TrpR
Inactive in the Freeform and active when complex with the co-repressor
