Primase
What is synthesizes a RNA primer at the 5' end of the leading strand and the 5' end of each Okazaki fragment of lagging strand?
100
What strand is synthesized continuously and what strand is synthesized discontinuously?
Leading strand: continuously
Lagging strand:discontinuously
100
What proteins are involved in the nucleotide excision repair?
What is nuclease enzyme, DNA polymerase and DNA ligase?
100
What is the shape of the replication fork?
What is a "Y" shape?
200
Helicase
What is unwinds parental double helix at replication forks
200
Why is the lagging strand synthesized as a series of fragments?
What is DNA polymerase proceed only in the 5' to 3' direction. The lagging strand proceeds in the opposite direction, from 3' to 5'?
200
What type of DNA repair is this?
What is mismatch repair?
200
What protects the genes of chromosomes from eroding way due to successive rounds of DNA replication?
What are telomeres?
300
Topoisomerase
What is relieves overwinding strand ahead of replication forks by breaking, swiveling and rejoining DNA strands
300
What is the first step in the replication of the lagging strand?
What is the synthesize of the RNA primer for the Okazaki fragment?
300
Nucleotide Excision Repair
What is nuclease remove the incorrect bases and and fill the gap with the correct nucleotides?
300
What do telomeres contain?
What is telomeres do not contain genes. They are composed of repetitive nucleotide sequences that do not contain genes?
400
Single-strand binding protein
What is binds to and stabilizes single-stranded DNA until it is used as a template
400
What is the difference between the way leading strand and the lagging strand are primed?
Each Okazaki fragment on the lagging must be primed separately. Only one primer is required in the leading strand.
400
Nuclease
What is an enzyme that cut out a segment of the strand containing the damage?
400
DNA poly III
What is synthesizes new DNA strand by adding nucleotides to an RNA primer?
500
DNA pol I
What is removes RNA nucleotides of primer from 5' end and replace them with DNA nucleotides added to the 3' end of adjacent fragment?
500
Okazaki fragments
What are short sequences of DNA nucleotides of the lagging strand that are synthesized discontinuously?
500
Mismatch Repair
What is enzymes remove and replace incorrectly paired nucleotides?
500
What protein if #5?
What is topoismerase?
