Mutagen is the name of environmental agents that can cause defects in genetic material.
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.
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
If a cell has accumulated DNA damage then the cells organelles might begin to not function correctly. This will slowly kill the cell.
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.
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.
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.
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.

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.

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.
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.
Alcohol can damage DNA, but it doesn't "kill" it in the way it might kill a cell. Ethanol, the type of alcohol found in beverages, can lead to the formation of harmful compounds that cause oxidative stress and DNA strand breaks. While cells have repair mechanisms to fix DNA damage, excessive alcohol consumption can overwhelm these processes, potentially leading to mutations and contributing to diseases such as cancer.
DNA cleavage is the breaking of the phosphodiester bonds that connect the nucleotides in a DNA molecule. It can occur naturally through processes like DNA replication and repair, or it can be induced in a laboratory setting using enzymes called restriction enzymes or other DNA-cleaving agents.
