What is the name of the enzyme that copies the sense strand to make mRNA?
RNA polymerase
How are errors in the replication process corrected?
"... errors are corrected in DNA is through the use of the enzyme DNA polymerase. This enzyme is the same one that matches nucleotides that create a new strand to the old strand of a molecule of DNA. After DNA polymerase creates the new molecule of DNA, it checks its work, to make sure that it didn't try to match a nucleotide with its incorrect pair." -taken from last editors paper.
How does the cell know which enzyme to make and how to make it?
Enzymes are proteins. Thus, DNA codes the enzyme's information to an mRNA strand, which then is translated by tRNA into an anticodon. This takes place on the ribosome.
What enzyme attaches new DNA nucleotides to make the new strand of DNA?
DNA polymerase
How does a DNA molecule make a cop of itself?
the DNA molecule split down the middle,where the bases meet. The bases on each side of the molecule are used as a pattern for a new strand.
What strand of DNA is used to make a complementary copy or to make a complementary mRNA molecule-?
The strand is called the parental strand. the gene being copied would depend on which protein is needed.
What strand of DNA is use to make a complementary copy or to make a complementary mRNA molecule?
The template strand is used to make a complementary copy. This is a type of DNA strand.
What is the name of the enzyme that copies the sense strand to make mRNA?
RNA polymerase
What Features of DNA replication make it semi-conservative?
the original strand serves as a temple for the new molecule.

Four subunits are needed to make a DNA molecule.?
Nucleotides Four nucleotides are needed to make a DNA molecule.
What enzyme attaches new DNA nucleotides to make the new strand of DNA?
DNA polymerase

How many strands of nucleotides does a molecule of RNA contain?
one strand can make up a RNA molecule
Molecule that binds to an enzyme?
a substrate =================================== or an "interacting molecule".
Give 2 explanations for the fact that only certain substrate molecules will fit into this part of the enzyme molecule?
A substrate molecule will only fit into the active site if it is a complimentary shape. Also the amino acids that make up an enzyme have positively and negatively charged chemical groups so in orderr for a substrate to fit its active site any electrical charges on the substrate molecule must not be repelled by like charges on the enzyme so the charged groups on the enzyme molecule and substrate molecule must attract one another
