What are enzymes that have a proofreading role in DNA replication?
DNA polymerases
DNA fingerprinting involves cutting DNA strands using which what?
Restriction enzymes
What enzymes help separarte the 2 strands of nucleotides on DNA?
DNA helicase
What enzyme do scientists use to cut genes out of strands if DNA?
restriction enzymes
How are individual DNA strands are constructed?
DNA replication duplicates the DNA strands. This process is accompanied by various enzymes such as DNA polymerase, Helicase, Topoisomerase.In labs they are constructred by Polymerase chain reaction(PCR).
How many strands of DNA are there in a DNA fingerprint?
1 strand of naked genomic DNA cut by certain enzymes.
How are restriction enzymes used to look for differences between DNA samples?
Restriction enzymes cleave, or open, the DNA so that a sample can be taken and gel electrophoresis can separate the strands of DNA. From there, DNA probes bind to certain strands in each sample and DNA fingerprints can show the differences.
What enzymes are responsible for replication of the DNA molecule?
Helicase is the enzymes that splits the double helix into two separate strands, and DNA Polymerase (as opposed to RNA Polymerase) joins the nucleotides together in the new strands being created.
What if your job among enzymes on the DNA replication team is to keep single DNA strands from?
C. straightener
A zebra cell is just about to replicate its DNA What happens first?
Enzymes unwind the DNA molecule into two strands.
What enzyme unzips the DNA molecule?
There are several enzymes that 'unzip' DNA. These enzymes are collectively known as DNA helicases. DNA helicases are helix-destabilizing enzymes that bind to DNA at the origin of replication and break hydrogen bonds, thereby separating the two strands. This allows RNA polymerase to begin transcription (copying) of the DNA sequence.
Enzymes that move along each of the DNA strands during replication adding nucleotides to the exposed bases?
DNA polymerases
