How are the new strands and the original strands of DNA divided between the two new cells?
The deoxyribon nucleic acid lines up in perfect formation and the spindle fibers come and rip apart the DNA now there are to complete copies of DNA
The site where the old DNA strands separate and new DNA strands will be synthesized is called the?
replication fork
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 chemical is an enzyme that connects the pieces of a new DNA strands?
DNA ligase
New DNA is replicated in strands complementary to old DNA because production of new DNA follows the rules of?
base pairing

What is the result when DNA ligase has completed its job?
Two new strands of DNA. <--- Gradpoint/NovaNet

DNA replication involves producing new copies of DNA molecules. How many individual DNA strands exist after one molecule of DNA has been replicated?
DNA is made of 2 strands so when it replicates the strands separate and 2 new strands complete the old strands. leaving 4 strands making 2 sets of DNA, both sets of DNA consist of one old strand and one new strand.- Sierra A. Buchanan
What is the enzyme that controls the synthesis of new strands of DNA called?
DNA polymerase
What chemical is an enzyme that connects the pieces of a new DNA strands?
DNA ligase
When DNA replicates the new strand is what to the original strand?
The original strands provide a template for making new strands.
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 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.
What is the process in which DNA is separated into two strands then produces two new complementary strands following the rules of base pairing?
DNA replication
What enzyme is responsible for catalyzing the formation of the two new DNA strands?
DNA polymerases
