Mutations can cause diseases such as cancer
Mutations cause certain traits.
DNA polymerase
Mutations are usually anomalies in the sequence of a particular strand of DNA. The change is the sequence can be of various kinds and their individual effects vary. Sometimes mutations occur but they are never expressed. In such cases, on the whole, the mutation has had no impact. Changes in a single nucleotide can change the reading frame for protein coding regions and can cause misreading of the genetic code. For example, nonsense mutations caused by the exchange of a nucleotide leading to a stop codon can cause truncation of a protein. On the other hand, we can have silent mutations which show no effect because the nucleotide that has been exchanged does not cause change in amino acid sequence. So this would be an example of a mutation which shows no effect.
Yes, chemicals in cigarette smoke, such as polycyclic aromatic hydrocarbons and formaldehyde, can interact with DNA and cause mutations. These mutations can lead to changes in the genetic information, which may increase the risk of cancer and other diseases.
Mutations can cause diseases such as cancer
While this question should be recategorized because external stimuli do not cause the mutations that result in hemophilia, there are many types of radiation that can cause gene mutations as well as chemical exposure. For example sun light is UV light radiation wich can cause mutations (for example the mutations that result in skin cancer).
Mutations cause certain traits.
Many herbicides and pesticides hit the nuclear material and cause mutations when used to protect crop plants. Apart from causing mutations these very chemicals are carcinogenic in nature and cause cancer.
it cause every cell
Some mutations cause cells to lose control over cell division

Natural radioactivity can cause spontaneous mutations in an organism's DNA. These mutations are often referred to as spontaneous mutations or radiation-induced mutations.
DNA mutations can cause genetic disorders such as cancer, Diabetes, and Asthma.
