old is broken but new is not

How many strands of DNA are used to make complementary strands of DNA?
Two strands of DNA are used to make complementary strands of DNA. One original strand serves as a template for the synthesis of a new strand, resulting in a double-stranded DNA molecule with base pairing between the original and newly synthesized strands.
The site where the old DNA strands separate and new DNA strands will be synthesized is called the?
The site where the old DNA strands separate and new DNA strands are synthesized is called the replication fork. This is where the enzyme DNA polymerase adds nucleotides to the growing DNA strand.
How can you tell the difference between a DNA molecule undergoing transcription and being replicated?
If the DNA molecule is undergoing transcription, then mRNA nucleotides will be forming along the anti-sense strand of DNA. If the DNA molecule is undergoing replication, new DNA nucleotides will be forming along both original strands of DNA.
How are the new strands and the original strands of DNA divided between the two new cells?
During cell division, the two new DNA strands (replicated DNA) are separated between the two new cells to ensure each cell receives a complete set of genetic information. This process occurs during the mitotic phase of cell division, where the replicated DNA is divided equally between the daughter cells to maintain genetic continuity.
What unzips DNA so it can duplicate?
Enzymes called helicases are responsible for unzipping the DNA double helix so that it can be duplicated. Helicases break the hydrogen bonds between the paired nucleotides of the DNA strands, allowing the strands to separate and serve as templates for the synthesis of new DNA strands during replication.
What is the difference between helicase and polymerase in DNA replication?
Helicase is an enzyme that unwinds the double-stranded DNA during replication, while polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides to the template strand. In simpler terms, helicase unzips the DNA, while polymerase builds new strands.

The site where the old DNA strands separate and new DNA strands are synthesized is called the replication fork. This is where the enzyme DNA polymerase adds nucleotides to the growing DNA strand.
Replication forks tend to?
Replication forks tend to unwind the DNA helix, separate the double strands, and synthesize new strands of DNA in opposite directions. They are formed during DNA replication and move along the DNA template strands as replication progresses.
What enzyme builds new DNA strands from existing strands during DNA replication?
DNA Polymerase III is responsible for adding new nucleotides to the strand being synthesised. Also involved in DNA replication are DNA Polymerase I which replaces primers with nucleotides, and DNA Ligase which joins fragments of DNA together.
How can you tell the difference between a DNA molecule undergoing transcription and being replicated?
If the DNA molecule is undergoing transcription, then mRNA nucleotides will be forming along the anti-sense strand of DNA. If the DNA molecule is undergoing replication, new DNA nucleotides will be forming along both original strands of DNA.
What is the result when DNA ligase has completed its job?
Two new strands of DNA. <--- Gradpoint/NovaNet

At the end of DNA replication two new strands of DNA have been produced giving a total of?
Two new DNA chains are formed at the end of DNA replication, both identical in sequence to the template (or parent) chain. These chains are composed of 2 complimentary strands. It is important to note that of the newly formed DNA chains, one strand is the same as the template strand and the other one is a newly synthesized one.
What is the difference between the Helicase and DNA polymerase enzme?
The helicase in a way unzipps the wound DNA. DNA Polymerase then matches the nucleotide bases with free floating one so that A matches with T (or in RNA U) and G matches with C. Creating two new strands of DNA and completing DNA replication.
What chemical is an enzyme that connects the pieces of a new DNA strands?
DNA ligase
