There is no single enzyme responsible for DNA duplication. But the most important ones are:

Helicase: it unwinds the DNA helix
RNA polymerase: adds the RNA primer
DNA polymerase: adds the complementary strand of DNA
Ligase: attaches the DNA fragments together

How are hydrogen bonds separated when DNA copies itself?

During DNA replication, hydrogen bonds between base pairs are broken by an enzyme called DNA helicase. This enzyme unwinds the double helix structure of DNA, separating the two strands. This allows for new complementary nucleotides to be added during the replication process.


What is an enzyme that copies DNA to make a molecule of RNA is?

The enzyme that copies DNA to make a molecule of RNA is called RNA polymerase. During the process of transcription, RNA polymerase binds to the DNA template strand and synthesizes a complementary RNA strand by adding ribonucleotides in the 5' to 3' direction. This process ultimately results in the formation of messenger RNA (mRNA), which carries genetic information from DNA to the ribosome for protein synthesis.


What separates DNA strands when DNA copies itself?

Topoisomerase is the enzyme that unwinds the DNA during replication. It binds to the DNA, and separates the double strands and form a replication fork. After which the primer bind to the start site, and DNA polymerase starts DNA synthesis.


What enzyme do you need to get a copy of DNA from mRNA?

The enzyme needed to make a DNA copy of RNA (including mRNA) is called reverse transcriptase. This enzyme is capable of synthesizing a complementary DNA strand from an RNA template, which is the first step in generating a cDNA (complementary DNA) library.


The process of copying the DNA molecule is called DNA?

replication. In this process, the two strands of the DNA molecule unwind and each strand serves as a template for the synthesis of a new complementary strand. This results in two identical copies of the original DNA molecule.

What enzyme is responsible for cutting DNA molecules?

The enzyme responsible for cutting DNA molecules is called a restriction enzyme.


What enzyme cuts and seals DNA?

The enzyme that cuts DNA is called a restriction enzyme, while the enzyme that seals DNA is called DNA ligase. Restriction enzymes cut DNA at specific sequences, creating breaks in the DNA strands, while DNA ligase seals these breaks by catalyzing the formation of phosphodiester bonds between the DNA fragments.
