In DNA replication, a new DNA has 1 parent strand and 1 new strand? Therefore, DNA replication is considered as ________.
Conservative
Semiconservative
Dispersive
This term refers to the separation of the two single strands of DNA that creates a ‘Y’ shape.
enzyme
unzip
A replication fork
What is the enzyme that helps helicase unzip DNA by relieving supercoiling?
Topoisomerase
Exonuclease
DNA Primase
DNA Polymerase
In what direction does the leading strand run?
3' ----> 5'
5' -----> 3'
It doesn't matter
Both directions
Each DNA molecule created contains one NEW strand and one OLD strand.
True
False
Okazaki fragments are found on the _______________ strand.
Leading
Lagging
A DNA nucleotide contains all of the following, except ______.
Deoxyribose
Phosphate group
Nitrogenous base
Cholesterol
Sometimes, DNA is called "semi-conservative." Why might this be?
The old strand is "conserved" and used to make the new strands.
Uracil is "conserved" in that it is only used to make the new strand.
ATP is "conserved" via the usage of facilitated diffusion.
Ligase is "conserved" in that it is denatured by the process.
What determines the code or information of a DNA molecule?
the shape (structure) of the nitrogen bases
the order (sequence) of the nitrogen bases
the color of the nitrogen bases
the frequency (number) of nitrogen bases
A process in which DNA has the unique ability to make an exact copy of itself is called ______.
