Cells that have accumulated too much chromosomal damage can do what?
If a cell has accumulated DNA damage then the cells organelles might begin to not function correctly. This will slowly kill the cell.
DNA cutting enzymes used in the repair of DNA damage?
DNA endonucleases are used to cut the DNA. They are specific enzyme that recognize the particular site of the DNA and digest them. DNA polymerase and DNA ligase are also involved in repairing DNA damage.
What is a DNA lesion?
DNA Lesions are sites of damage in the base-pairing or structure of DNA.
What is the name given to anything that causes mutation?
Mutations happen for several reasons. 1. DNA fails to copy accurately. Most of the mutations that we think matter to evolution are "naturally-occurring." For example, when a cell divides, it makes a copy of its DNA-and sometimes the copy is not quite perfect. That small difference from the original DNA sequence is a mutation. 2. External influences can create mutations. Mutations can also be caused by exposure to specific chemicals or radiation. These agents cause the DNA to break down. This is not necessarily unnatural-even in the most isolated and pristine environments, DNA breaks down. Nevertheless, when the cell repairs the DNA, it might not do a perfect job of the repair. So the cell would end up with DNA slightly different than the original DNA and hence, a mutation.
Why would DNA polymerase be useful in a potential anti cancer drug?
DNA polymerase can fill the gaps in the DNA that are left by removal of damage bases. DNA polymerase can help cancer cells to tolerate DNA damage.
How can mutation occurs in cells?
Mutations can be inherited. This means that if a parent has a mutation in his or her DNA, then the mutation is passed on to his or her children.Mutations can be acquired. This happens when environmental agents damage DNA, or when mistakes occur when a cell copies its DNA prior to cell division.

What happens in a cancer growth?
When the UV rays hit your skin it can cause damage to your DNA cells. this is called getting sunburned. when you get too much sun exposure and your DNA cells are damaged beyond repair then this might cause your DNA cells to break apart. this will cause more cells to form and when the cells reach the flesh it forms skin cancer.
What might happen if apoptosis did not occur in cells that have significant DNA damage?
Most likely cancer would arise if apoptosis did not occur in cells that have significant DNA damage.
Why would DNA polymerase be useful in a potential anti cancer drug?
DNA polymerase can fill the gaps in the DNA that are left by removal of damage bases. DNA polymerase can help cancer cells to tolerate DNA damage.
Where is the checkpoint for DNA damage?
g1
Should you vortex the solution containing DNA?
No, vigorous vortexing can damage the DNA
What is a change in the sequence of bases in DNA molecules called?
The change in the order of the bases in a DNA molecule is called a mutation. Such changes may happen because of damage to genomes, replication errors, or insertion or deletion of nucleotide bases.
Ultraviolet light can damage bacterial cells by causing two adjacent nucleotides on a DNA strand to bond called?
Thymine dimerazation.
