BIO 111 EXAM 5 TEST QUESTIONS WITH ACCURATE SOLUTIONS
blending inheritance
believed an offspring's traits are a mixture of the parents - black sheep+white sheep= gray
sheep
inheritance of acquired characters
claimed that traits present in parents are modified and are passed on in modified form -
giraffe necks get longer
DNA polymerase I
In the replication process, RNase H removes the RNA primer (created by Primase) from the
lagging strand and then Polymerase I fills in the necessary nucleotides between the
Okazaki fragments (see DNA replication) in a 5'→3' direction, proofreading for mistakes as it
goes.
DNA polymerase III
DNA polymerase III holoenzyme is the enzyme mainly accountable for replicative DNA
synthesis in E. Coli. It carries out primer-initiated 5' to three' polymerization of DNA on a
single-stranded DNA template, as well as three' to five' exonucleolytic enhancing of
mispaired nucleotides.
sliding clamp
A DNA clamp, also known as a sliding clamp, is a protein fold that serves as a processivity-
promoting factor in DNA replication. As a critical component of the DNA polymerase III
, holoenzyme, the clamp protein binds DNA polymerase and prevents this enzyme from
dissociating from the template DNA strand.
primase
DNA primase, also called as DNA primerase, is an enzyme involved in the replication of
DNA. DNA primase is a type of RNA polymerase which creates an RNA primer (later this
RNA piece is removed by a 5' to 3' exonuclease); next, DNA polymerase uses the RNA
primer to replicate ssDNA.
helicase
Helicases are enzymes that bind and may even remodel nucleic acid or nucleic acid
protein complexes. There are DNA and RNA helicases. DNA helicases are essential during
DNA replication because they separate double-stranded DNA into single strands allowing
each strand to be copied.
SSBP
Protein that binds to single-stranded DNA usually near the replication fork to stabilize the
single strands.
topimerase
an enzyme that alters the supercoiled form of a DNA molecule.
normal distribution
