A substitution mutation in genetics is where one of the nucleotide bases of DNA is swapped for another. These mutations may or may not affect the protein that is being coded.

What is a mutation that helps an organism to live and survive in its environment?
The mutations or other changes are adaptations.
What is a synonym for transfer?
substitution, change, shift
Why is nuclear radiation dangerous to human being'S?
Nuclear radiation can cause genetic mutations in our DNA, which can cause cancers. If the genetic mutations occur in the germ cells, then our gametes (sperm and egg cells) could have genetic mutations that could be passed on to our offspring. Also, if radiation levels are high enough, people can get radiation sickness, which can be fatal.
Why vacuume tubes are replaced by transistors?
Many factors encourage this substitution. BUT not all - many high power vacuum tubes are still used. The reasons for the substitution include weight, power consumed, reliability, space requirements, high frequency response, the ability to form complex circuitry on a single substrate. (e.g. a microprocessor). Cost and miniaturisation were also driving factors. Transistors are cheaper to make and take up less room. Ironically Vacuum tubes are LESS susceptible to EMP caused by nuclear explosions. So are sometimes used in (Russian) jet fighter electronics.
Gamma rays are dangerous because they?
Because unlike alpha and beta particles emitted by sources of radiation it can penetrate through the skin instead of being blocked by it. The radiation causes unnecessary divisions and multiplication of your cells and DNA. The mutation caused by it can lead of weaker essential organs and functions. And mutations may cause diseases and cancer.
Changes in a DNA sequence caused by substitution of one nucleotide for another?
Point mutations
What are 3 types of mutation?
Three types of gene mutations are substitution, insertion, and deletion. Another gene mutation would be frame shift. All these mutations can cause deformities of the gene.
What is the name for a change in DNA?
The answer is Mutations! The 3 basic types of mutations are substitution, insertion, and deletion.
What are 3 genetic mutations?
substitution and deletion, frameshift, translocation
What type of mutations exist in sickle cell allele?
substitution See the attached link.
What 3 mutations happen during cell division?
Insertion, Deletion, and Substitution
The substitution of one base for another during DNA replication is an example of what?
Mutations
Which of the following statements about mutations and genetic disease are correct?
Mutations can result from spontaneous events or external mutagens. A change in DNA sequence may change the pattern of protein folding, resulting in genetic disease. Some genetic diseases may be caused by the substitution of only one incorrect amino acid in a protein. It is possible for the substitution of one base for another to have no effect on an organism.
Is it true or false that mutations that result from the substitution of the nitrogen base for another are called deletions?
TRUE
What are three main types of gene mutations what happens in each gene?
They are Substitution, Insertion, and Deletion.
What are 4 type of mutation?
Four types of chromosomal mutations include substitution, insertion, deletion, and frame shift. These mutations can be either positive of negative to the organism.
What kind of mutation will result from the mistake made during DNA replication in the nucleotide sequence above?
The specific type of mutation resulting from a mistake during DNA replication will depend on the nature of the mistake and the type of nucleotide substitution that occurred. Some possible types of mutations include point mutations (such as a substitution, insertion, or deletion of a single nucleotide), frameshift mutations, or silent mutations.
