When chromosomes are stained with heterochromatin; euchromatin
dyes, ___________ stains darkly, whereas
_________ stains lighter.
What is the complementary DNA 3' - TCCGCCTAGCTGGCATG - 5'
strand to the following strand: 5' -
AGGCGGATCGACCGTAC - 3'?
You are working with a novel organism 30%
with double stranded DNA and you
discover that this organism has 20%
adenine in its DNA. What percentage
of cytosine do you expect that this
organism has in its DNA?
Imagine you are able to watch DNA ligase
replication under a microscope in a
mutant strain of bacteria. DNA
replication appears to proceed
normally, but at the end of the
replication cycle, there are some
regions of the DNA that appear to be
fragmented and not joined together
along the backbone of the DNA
molecule. Which enzyme is most likely
missing in this bacterial strain?
,If the DNA fragments below were run CC
on a sequencing gel, which fragment
would run nearest to the bottom of
the gel?
Replication occurs at a _________. replication fork
The DNA double helix is separated DNA Helicase
into single strands by the enzyme _____.
Short segments of RNA, called ______, RNA primers
are synthesized
Newly-exposed, unreplicated DNA is binding proteins
protected by _______
The enzyme that synthesizes the short primase
segments of RNA is called a
New DNA is synthesized in the 5' to 3'
_____________ direction
The enzyme that catalyzes new DNA DNA polymerase
synthesis is ________
Fragments of discontinuous DNA Okazaki Fragments
synthesis are called _________
Gaps in the sugar-phosphate DNA ligase
backbone of DNA are closed by _______
What type of structure do purines two-ring
have?
Which of the following statements is DNA polymerase proofreads DNA, correcting
true in DNA replication? mismatched nucleotides
, In a eukaryotic genome, DNA multiple sites along the length of each chromosome.
replication starts at
Because DNA strands are antiparallel, continuously on one strand and discontinuously on
DNA replication at a single replication the other.
fork proceeds
Okazaki fragments are small pieces of DNA
The first and best-known DNA the polymerase chain reaction
amplification technique is __________.
A nucleotide consists of one deoxyribose sugar, one nitrogenous base, and
one phosphate group.
Identify each of the components of a
nucleotide.
Identify the components of DNA by
dragging and dropping the labels to
the correct locations on the figure.
Which chemical is not a part of DNA? ribose
Which base pair is complementary? A and T
Purines and pyrimidines refer to the nitrogenous bases
__________ of the DNA molecules.
In a molecule of DNA, purine bases hydrogen
form __________ bonds with pyrimidine
bases.
The nitrogenous bases adenine and a purine and a pyrimidine, respectively.
