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
What enzyme separates DNA during replication?
The enzyme that separates DNA during replication is called helicase. It unwinds and separates the double-stranded DNA into two single strands, allowing each strand to serve as a template for the synthesis of new complementary strands. This process is essential for accurate DNA replication and ensures that the genetic information is faithfully copied.
What is the role of the helipads enzyme in DNA replication?
The helicase enzyme plays a crucial role in DNA replication by unwinding the double-stranded DNA molecule at the replication fork. It separates the two strands, allowing them to serve as templates for the synthesis of new complementary strands. This unwinding is essential for the DNA polymerase enzyme to access the single-stranded DNA and synthesize new DNA during replication. Without helicase, DNA replication would be impeded, preventing cell division and proper genetic inheritance.
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 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.

Which enzyme is responsible for facilitating the hydrogen bonding between nucleotides in a new molecule?
the DNA polymerase III
What is the role of the helipase enzyme in DNA replication?
Helicase is an essential enzyme in DNA replication responsible for unwinding the double-stranded DNA molecule. It separates the two strands by breaking the hydrogen bonds between the nucleotide bases, creating a replication fork. This unwinding allows other enzymes, such as DNA polymerase, to access the single-stranded DNA templates for synthesis of new complementary strands. Without helicase, DNA replication cannot proceed efficiently.
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.
