Viruses and chemical exposure can cause mutations in proto-oncogenes which can lead to?
onocogenes.
Process:
-PO (proto-oncogenes) are moved (closer to promoter/enhancer)
-More PO is made
-Proteins are made in excess (in more excess if it's been in excess from
previous step)
-Mutations at pts
-At PO, causing increase expression
-At coding gene, causing gene protein to resist degeneration

What are 4 things that contribute to mutation?
DNA replication errors during cell division can introduce mutations. Exposure to mutagens such as radiation, chemicals, and viruses can cause DNA damage and mutations. Environmental factors like UV light can induce mutations in DNA. Inherited genetic mutations passed down from parents can contribute to mutations in offspring.
Can mutations occur in jellyfish?
Mutations happen in ALL living things (and also in viruses)!!!!!!
What effect can mutations have on viruses?
i think that most of the mutated genes have more then one thing wrong with them
Are viruses less harmful after mutations occur?
Not necessarily; mutations in viruses can lead to changes in their virulence. While some mutations may result in a less harmful strain, others can increase a virus's ability to spread or evade the immune system, potentially making it more dangerous. The impact of mutations varies widely depending on the specific virus and the nature of the changes. Overall, each mutation must be evaluated individually to determine its effects on harmfulness.
Normal cell become cancer when the cell does what?
Normal cells can become cancerous when they undergo genetic mutations that cause them to grow and divide uncontrollably. These mutations can be caused by various factors such as exposure to carcinogens, viruses, or genetic predisposition. The loss of mechanisms that regulate cell growth and division, as well as the ability to repair DNA damage, can contribute to the development of cancer.
Can science mutate humans?
Mutations arise as a result of exposure to radiation, chemicals, and viruses. Many different things might act as a mutagen. Science itself probably does not cause mutations.
What can cause changes in DNA sequences?
mutations

What does the process of carcinogenesis usually begin with?
Carcinogenesis usually begins with the accumulation of genetic mutations in a cell that lead to uncontrolled cell growth and division. These mutations can be caused by various factors such as exposure to carcinogens, radiation, or viruses.
What environmental factors cause mutations?
Mutagens are chemical or physical factors that increase the rate of mutation. Some are natural, and some are synthetic. Some examples of mutagens are: - Cosmic rays - Some viruses - Harmful atomic radiation - Recreational drugs - Tobacco - Alcohol - Pesticides - Asbestos - Soot
What is one way mutations happen?
Mutations can occur spontaneously during DNA replication when errors are made, such as base substitutions or insertions/deletions. They can also be induced by external factors like radiation, chemicals, or viruses.
What can cause mutations in the DNA structure?
Mutations in DNA can be caused by errors during DNA replication, exposure to mutagenic agents such as chemicals, radiation, or viruses, and spontaneous changes due to cellular processes. These mutations can lead to changes in the genetic code, potentially impacting protein function and biological processes.
What is the source of mutation?
Pesticides are believed to be one source of frog mutation.
What effect can mutations have on viruses?
i think that most of the mutated genes have more then one thing wrong with them
Can a person become immune to common cold viruses?
Repeated exposure to viruses causing colds creates partial immunity.
Normal cell become cancer when the cell does what?

These mutations can be caused by various factors such as exposure to carcinogens, viruses, or genetic predisposition. The loss of mechanisms that regulate cell growth and division, as well as the ability to repair DNA damage, can contribute to the development of cancer.
