Biochemistry Exam need to Study Questions and
Answers Verifies 100% Correct
semi conservative
DNA replication is ___________, meaning that each new duplex has one original
(parent) strand and one new strand.
template
Because the two parent strands are separated during replication and the base pairing is
predictable, each parent strand can serve as a ____________for the new strand
synthesis.
helicase
unwinds the double stranded DNA to allow for replication, but this is not a problem for
the DNA polymerase.
Nucleotide excision repair
_______________is used to repair deletions, insertions, and helix-distorting lesions,
such as thymine dimers.
complementary strand
a strand of DNA that is the exact match of another
complementary sequence
Nucleic acid base sequences that can form a double-stranded structure by matching
base pairs.
mRNA DNA sequence
The use of U instead of A, starts from right to left.
, 32
How many DNA copies after 4 complete PCR cycles?
DNA polymerase
This recognizes the primers and uses the available dNTPS to replicate the template DNA
sequence.
nonsense mutation
missense mutation
frameshift mutation
silent mutation
x linked recessive
autosomal dominant
autosomal recessive
x linked dominant
SIRT1, SIRT2
associated with chronic exposure to cocaine and drug addiction, the nucleosomes
become widely spaced.
alternative splicing of mRNA
Alternative combination of exons within the same
gene are linked together.
base excision repair
-nucleotide is cut out and replaced with correct nucleotide
