What is the first step in DNA synthesis?
The first step in DNA synthesis is the unwinding of the double-stranded DNA molecule by an enzyme called helicase. This process separates the two strands of DNA, creating a replication fork where the synthesis of new DNA strands can occur.
Is a new enzyme molecule needed each time a reaction occurs?
yep
When DNA replication occurs the enzyme which separates the two side of the helix is called?
The enzyme that separates the two strands of the DNA helix during replication is called helicase. It unwinds the double helix by breaking the hydrogen bonds between the base pairs, allowing each strand to serve as a template for the synthesis of a new complementary strand.
What does a enzyme-substrate complex do?
An enzyme-substrate complex is formed when a subtrate molecule binds with the active site of an enzyme that is of similar shape and size. The active site of the enzyme will alter slightly to combine with the substrate molecule. This will put an strain on a particular bond of the substrate molecule, which will lower the activation energy for the reaction as the bond will break more readily. The substrate is then catalysed.
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.

What happens first at each origin replication?
Enzymes unwind DNA!
What molecule will proofread the new DNA strands?
RNA polymerase is the enzyme that connect the new nucleotides together and proofreads them.
When DNA replication occurs the enzyme which separates the two side of the helix is called?
The enzyme that separates the two strands of the DNA helix during replication is called helicase. It unwinds the double helix by breaking the hydrogen bonds between the base pairs, allowing each strand to serve as a template for the synthesis of a new complementary strand.
Which enzyme is responsible for facilitating the hydrogen bonding between nucleotides in a new molecule?
the DNA polymerase III
A zebra cell is just about to replicate its DNA What happens first?
First, the DNA double helix unwinds and separates into two strands. Then, each strand serves as a template for the synthesis of a new complementary strand. This process is carried out by enzymes that help assemble the new DNA strands.
What happens when a DNA molecule unzips?
DNA splits, and mRNA and tRNA are there to create new strands for the new replicated DNA strand. This is what happens prior to mitosis in cell division.
Which enzyme is responsible for creating the covalent bonds that connect the sugar-phosphate backbone of the new DNA molecule?
DNA ligase is the enzyme responsible for creating the covalent bonds that connect the sugar-phosphate backbone of the new DNA molecule during DNA replication and repair processes. It seals the nicks between adjacent nucleotides to form a continuous DNA strand.
What separates New Jersey and Pennsylvania?
The natural boundary that separates New Jersy from Pennsylvania is the Delaware river
What separates christchurch and westport in New Zealand?
The Southern Alps of New Zealand separates Christchurch and Westport.
What happens to the enzyme after the substrate is changed?
enzyme works as a catalyst before and after the reaction it is preserved
