what type of mutation likely causes a temperature sensitive allele?
Mutations result from: viruses, a jumping gene, mutagenic chemicals, or exposure to radiation, as well as from errors that may occur during DNA replication or meiosis in the production of gametocytes. It can be induced by the organism itself by cellular processes such as hypermutation.
what type of mutation likely causes a temperature sensitive allele?
Most temperature-sensitive mutations affect proteins, and cause loss of protein function at the non-permissive temperature. The permissive temperature is one at which the protein typically can fold properly, or remain properly folded. At higher temperatures, the protein is unstable and ceases to function properly. These mutations are usually recessive in diploid organisms. Temperature sensitive mutants arrange a reversible mechanism and are able to reduce particular gene products at varying stages of growth and are easily done by changing the temperature of growth.
what type of mutation likely causes a temperature sensitive allele?
Temperature sensitive mutations are usually missense mutations, which then will harbor the function of a specified necessary gene at the standard, permissive, low temperature.
