Translation and Transcription Flashcards
helicase
unwinds DNA
topoisomerase
relieves tension
Primase (RNA Primer)
is the RNA primer
DNA Pol
Makes new DNA
DNA ligase
links okazaki fragments
SSBI (Single stranding binding proteins)
keeps DNA apart
DNA Polymerase can fix mistakes
called proofreading
endonucleases have _____ sequences
palindromic (i.e. GCGC) (cuts out specific sequences in DNA errors)
lac operon
inducible system
trp operon
repressive system
RNA Polymerase I, II, and III (functions?)
rmt
I=rRNA
II=mRNA
III=tRNA
Transcription ends with which three gene mods?
5 prime cap
3 poly A tail
splicing
pi definition
pH at which amino acid is neutral
low pH (amino charge)
+ charge
high PH (amino charge)
- charge
acidic aminos (how to find pI)
use two lowest pkA values
basic aminos (how to find pI)
use two highest pkA values
exonuclease
consume from the ends of RNA
