What are the deleted segments of DNA called?
Deleted segments of DNA are called deletions. Deletions involve the loss of a segment of DNA from a chromosome, which can lead to genetic disorders or changes in an organism's traits. This type of mutation can be caused by errors during DNA replication or exposure to mutagenic agents.
Common mutagenic agents include?
In genetics, a mutagen (Latin, literally origin of change) is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations cause cancer, mutagens are therefore also likely to be carcinogens. Not all mutations are caused by mutagens: so-called "spontaneous mutations" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination. This is from wiki hope it helps
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.
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.
What are the Chemicals that react with DNA?
Chemicals that can react with DNA include alkylating agents (e.g. EMS), intercalating agents (e.g. ethidium bromide), oxidative agents (e.g. hydrogen peroxide), and reactive oxygen species like hydroxyl radicals. These chemicals can lead to DNA damage such as base modifications, strand breaks, and crosslinks.
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.

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.
What agents do not cause mutations in DNA?
The height of mount Everest is unlikely to cause mutation in DNA. You may find this answer surprising but it is I assure you a true answer. Your problem is that you asked your question in the negative (What is UNLIKELY) which means that just about anything in the universe is a valid answer.
Why are mutations called agents of change?
Mutations are called agents of change because they introduce new genetic variations into an organism's DNA, leading to different traits or characteristics. These changes can result in evolution and adaptation to environmental pressures, making mutations essential for genetic diversity and the survival of species.
Where is the checkpoint for DNA damage?

What is an example of environmental factors that cause mutations in DNA?
Environmental factors that can cause mutations in DNA include exposure to radiation, such as ultraviolet (UV) light and ionizing radiation, which can damage the DNA structure. Additionally, chemical agents like certain pesticides, heavy metals, and industrial pollutants can lead to alterations in the DNA sequence. These environmental mutagens can result in changes that may contribute to diseases, including cancer.
