What enzyme is responsible for cutting DNA molecules?
The enzyme responsible for cutting DNA molecules is called a restriction enzyme.
What is the best explanation for why a restriction enzyme does not cut the DNA of the cell that produces it?
Restriction enzymes are made by cells to protect their own DNA from being cut. These cells produce a modification enzyme that adds a methyl group to specific sites on their own DNA sequence, which prevents the restriction enzyme from cutting. This process is known as "methylation protection."
What does a restriction enzyme do in the process of DNA manipulation?
A restriction enzyme is a protein that cuts DNA at specific sequences, allowing scientists to manipulate and study DNA by cutting it into smaller fragments.
Why ligation can be considered the reverse of the restriction enzyme process?
Restriction enzymes cuts out a specific short nucleotide sequence while as the process of ligation, DNA ligase joins them together. So ligase can be considered the reverse of the restriction enzyme process as it joins DNA fragments together instead of cutting them out.
An enzyme that cuts double-stranded DNA at specific nucleotide sequences?
Such an enzyme is called a restriction endonuclease

What tool to use when cutting plasmid?
a Restriction Enzyme

Why did you cut both segments of DNA with the same restriction enzyme?
You use the same enzyme inn order to get the same restriction and binding sites.
What is the restriction site of the restriction enzyme Hae III?
The restriction site of Hae III is GGCC. It cuts between the G and the C. This produces blunt ends.
What is the advantage of restriction enzyme sites being palindromic?
Palindromic restriction enzyme sites are advantageous because they read the same on both strands of DNA, making them easier to identify and use for cutting DNA at specific sequences. This symmetrical nature ensures that the enzyme can cleave at a particular site regardless of the orientation of the DNA fragment.

How does enzyme restriction limit the affect of a virus?
Enzyme restriction acts as a defense mechanism by cutting viral DNA at specific recognition sites, preventing the virus from replicating effectively in the host cell. This limits the virus's ability to spread and cause infection.
Which restriction enzyme did you use to cut the DNA?
The restriction enzyme used to cut the DNA was EcoRI.
How does the process of restriction enzyme cutting contribute to the manipulation of DNA sequences in genetic engineering?
Restriction enzymes are used in genetic engineering to cut DNA at specific locations, allowing scientists to manipulate and rearrange DNA sequences. This cutting process helps to insert new genes, remove unwanted sections, or study specific gene functions. Overall, restriction enzyme cutting plays a crucial role in the precise editing and modification of DNA sequences in genetic engineering.
