If the new DNA strand is being built continuously toward the replication fork, that strand represents the ___
lagging strand
template strand
coding strand
leading strand
ATG TGA CAG
Which of the following is NOT a part of the DNA nucleotide?
Deoxyribose sugar
Phosphate group
Nitrogenous base
Lysine amino acid
How is the instructions for your traits carried on a DNA molecule?
Sequence of the nitrogen bases
In the Deoxyribose Sugar
In the bond between the phosphate and the sugar
In the phosphate group
Which of the following enzymes adds complementary nucleotides to the DNA template strands?
primase
helicase
topisomerase
DNA polymerase
Why are RNA primers added?
so that primase feels important
DNA polyermase needs a starting point
instructs helicase where to stop unzipping
holds ligase in place
What are the three components of a nucleotide?
sugar, hydrogen, nitrogen base
sugar, oxygen, nitrogen base
sugar, phosphate, nitrogen base
sugar, phosphate, protein
The picture below shows the steps of DNA replication beginning with step one and ending with step three.
Because you are reusing the old, or parent, DNA strand DNA replication is said to be
Semi- Conservative
Semi-discontinuous
Continuous
Fully-Conserveative
Which is the second step in DNA replication ?
DNA Helicase unwinds original DNA strand
RNA Primase lays down RNA primer for new nucleotide bases.
DNA polymerase builds new strands by bring in new nucleotide bases.
Ligase knits together fragments on lagging strand
