Test #3- Replication Flashcards
Initiation proteins
Multi enzyme complex
What do helicase do?
they unwind the helix on the 5’ strand only
What do single-strand binding proteins do?
they help separates DNA strand
What do Topoisomerases do?
They iron out the coiled unwinding tube
What is NTP?
(nucleoside+ phosphate)= nucleotide ATGC
what is dNTP?
deoxylose nucleotide
What does Primase do?
synthesizes RNA at 5’ end (PRIMER)
What does DNA pol III do?
synthesizes new DNA
What dos DNA pol I do
Removes RNA
What does DNA polymerase do?
Proofreads and is a side clamp
What segments does the lagging strand have?
okazaki segments
Can DNA pol III remove the previous RNA primer?
NOPE
Can DNA pol I remove the previous RNA primer?
YES
What does DNA ligase do?
it seals the gap
Can RNA proofread?
NO
What can DNA polymerase do if it realizes a mistake?
it can go back a little and chop it out right after it was inserted –called 3’–5’ exonuclease activity
