MBS EXAM 2 QUESTIONS WITH
DETAILED VERIFIED ANSWERS
(100% CORRECT ANSWERS)
Are the origins of replication always active? - correct answer-
No, they are not
As histones are released - correct answer- Chaperone grabs
and places it behind it
As new DNA is synthesized - correct answer- New histones
are added
Base damage is repaired by - correct answer- Repaired by
direct base or base excision repair
base excision repair - correct answer- DNA repair that first
excises modified bases and then replaces the entire nucleotide
ChIP-Seq - correct answer- identifies DNA binding sites of
transcription factors, tells you the specific protein
, ChIP-Seq - correct answer- Position of DNA where protein
binds (specific protein)
Chromosomes end - correct answer- In 3' extension,
repeated sequence to let DNA keep going
Direct Base Repair - correct answer- Some cellular processes
can repair specific bases which have been covalently damaged.
DNA binding (EMSA) - correct answer- How well DNA binds,
mix and check for shift and see if they bind together
EMSA - correct answer-
Exonuclease chews which end of old DNA? - correct answer-
5' end, but cannot do this to the new strand because it has RNA
on 5' end
H2A and H2B - correct answer- displaced as dimers ahead of
the fork, stick together
