bisc 261 la tech Test with Questions with
100% Correct Answers
a complex process involving numerous proteins which help ensure accuracy,
two strands separate each serving as a template - Answer dna replication
dna in most bacteria is - Answer circular
replication fork - Answer where dna is unwound
replicon - Answer portion of the genome that contains an origin that is replicated as a
unit
dna polymerase III holoenzyme - Answer complex of 3 core enzymes and several
other protiens
helicases - Answer unwind DNA strands
single stranded DNA binding proteins (SSB) - Answer keep strands apart for
replication to occur
, topoisomerases - Answer relieve tension from rapid unwinding of double helix,
prevents supercoiling
DNA gyrase - Answer change the structure of dna by transiently breaking one or
two strands without altering the nucleotide sequense of dna
primase - Answer synthesizes short complementary strands of rna primers needed by
dna polymerase
dna polymerase sythesis is in __ to __ direction only - Answer 5' to 3'
Okazaki fragments - Answer Small fragments of DNA produced on the lagging strand
during DNA replication, joined later by DNA ligase to form a complete strand.
proofreading - Answer Carried out by DNA polymerase III
Removal of mismatched base from 3' end of growing strand by exonuclease activity
of enzyme
This activity is not 100% efficient
catenanes - Answer form when the two circular daughter chromosomes do not separate
eukaryotes have ___ ___ chromosomes - Answer multiple linear
when and who observed the change of nonvirulent organisms into virulent ones via
origins of replication are marked by a complex of protiens called - Answer origin
recognition complex (ORC)
