Which type of mutation has no effect on protein function?
A point mutation that has no overall effect on a protein’s function is called a silent mutation.
Sometimes a silent mutation results in the same exact sequence of amino acids.
That’s what happened here..
What induces mutations?
Mutations can be induced by several methods. The three general approaches used to generate mutations are radiation, chemical and transposon insertion. The first induced mutations were created by treating Drosophila with X-rays. Using this a pproach Mueller to induce lethal mutations.
Do mutants really exist?
“Mutants are actually extremely common,” says OMRF scientist Dr. Chris Sansam. “Someone without any mutations would be the real anomaly.” Mutations are changes to a person’s genetic code, and they can come about from exposure to an external environmental factor, such as cigarette smoke or radiation.
What mutations have no effect?
The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.
What does a silent mutation do?
A silent mutation is a change in the sequence of nucleotide bases which constitutes DNA, without a subsequent change in the amino acid or the function of the overall protein. … A silent mutation can be caused many ways, but the key point is that it does not change the function of the amino acid or subsequent proteins.
