What can cause changes in DNA sequences?
mutations
Sometimes mutations in DNA can cause control of the cell cycle to fail. What might happen if such a mutation occurred in a person's DNA?
The failure of DNA replication during the cell cycle can cause mutations. If such mutations occurred in a person's DNA, the person can end up getting cancer.
Can mutations cause changes in DNA sequences?
mutations
Why dont all mutations cause cancer?
Mutations in the DNA can cause cancer, but it's not the only cause of cancer. Did you know you can get cancer if you are exposed to coals and tars too long?
DNA mutations can lead to genetic disorders diseases or even the death of an organism Which of the following factors is most likely to cause a mutation in DNA?
DNA mutations can lead to genetic disorders, diseases, or even the death of an organism. Which of the following factors is most likely to cause a mutation in DNA?
What can cause changes in DNA sequences?
mutations
How can DNA-level mutations affect the structure of proteins?
DNA is formed out of proteins, mutations can cause the bonds between the chains to loosen or not form at all. It may also cause additonal bonds forming and changet the order of amino acids involved in the chain.
Does gene mutations only temporarily change DNA structure when it repairs itself?
Mutations are permanent.
How can mutations cause genetic mutations in spite of your body's DNA repair enzymes?
Mutagens cause a change in DNA and by this way they can produce mutant DNA repair enzymes.
What cell cause mutations?
DNA polymerase
Sometimes mutations in DNA can cause control of the cell cycle to fail. What might happen if such a mutation occurred in a person's DNA?
The failure of DNA replication during the cell cycle can cause mutations. If such mutations occurred in a person's DNA, the person can end up getting cancer.
What are some of possible consequence of mutations?
DNA mutations can cause genetic disorders such as cancer, Diabetes, and Asthma.
Can mutations cause changes in DNA sequences?
mutations
What is one way that can occur in a DNA sequence?
Mutations (point mutations, inversions, translocations...) cause changes in DNA Simply stated, a mistake made while DNA copies causes changes in DNA.
Describe the enviormental factors that could result in mutations?
Chemical mutagens are chemicals that cause mutations in DNA. They can bind with DNA, take the place of base pairs (base analogs), or alter the structure and bonding properties of bases (such as nitrous acid).Ionizing radiation can cause mutations in DNA also. This includes gamma rays found in sunlight. The radiation causes some compounds to become free radicals, which have unpaired electrons and are very reactive chemically. In cells these radicals can react with sections of DNA and cause mutations.*Ionizing radiation is why bacteria are killed by sunlight.
How does chemestry affect cancer?
Chemicals that do not cause cancer by themselves but can act with another chemical to cause cancer (cocarcinogens). Damage to DNA in cells can lead to cancer. ... Unrepaired DNA damage can lead to mutations, or changes, in genes, and mutations in certain genes can cause cancer. You can also inherit mutations.
What is one way that changes occur in a DNA Sequence?
Mutations (point mutations, inversions, translocations...) cause changes in DNA Simply stated, a mistake made while DNA copies causes changes in DNA.
