The types of point mutations are: base-pair substitution, insertions, deletions, and frameshift mutations. In base-pair substitution, one nucleotide and its corresponding partner are replaced with another pair of nucleotide. In insertion, nucleotide pairs are added to a gene. In deletion, nucleotide pairs are taken out of a gene. Frameshift mutation happens as a result of insertion or deletion when more or less than three (or a multiple of three) nucleotide pairs are added to or taken from a gene.
The three types of point mutations are substitutions, insertions/deletions, and mutations. Substitution is where a nucleotide and its corresponding partner nucleotide are replaced with another pair of nucleotides. Insertions/deletions cause frameshift mutations when pairs of nucleotides that are not in multiples of 3 are taken from or added to a gene. Mutations can be spontaneous or a result of mutagen interaction.

What are two types of mutation?
From another angle: beneficial and detrimental.
When would a mutation in DNA not cause a change in how the gene is expressed or in which proteins are made?
If a point mutation occurs in a location that is not critical to the structure and function of the protein, it will not change the way the gene is expressed. Also, since most amino acids have more than one codon, if the point mutation resulted in a codon for the same amino acid without the mutation, it will not change the way the gene is expressed.
The original source of genetic variation that serves as the raw material for natural selection is what?
Generally, mutation.
Why is mutation important to spectation?
Without mutation there can be no evolution. Without evolution there can be no speciation.
A change in the nucleotide base sequence of gene or DNA molecule is called a what?
this is called a mutation
What are two types of mutation?

Name 2 major types of mutation?
i] spontaneous mutation ii] induced mutation iii] germinal mutation iv] somatic mutation v] chromosomal mutation vi] gene mutation are the some of the major types of mutation......
What type of mutation is a point mutation?
A point mutation is a type of mutation that involves a change in a single nucleotide in the DNA sequence. This can result in different types of mutations such as substitutions, insertions, or deletions of nucleotides.
A change in a single nucleotide in DNA-?
A mutation
A mutation that involves a single nucleotide is called a(an)?
A mutation that involves a single nucleotide is called a point mutation. This type of mutation can include substitutions, insertions, or deletions of a single nucleotide in the DNA sequence.
A mutation that involves one or a few nucleotides is called a?
Sorry to burst the persons bubble that said frameshift mutation but its wrong. Point mutation-gene mutation involving changes in one or a few nucleotides. point mutation
What is a mutation called that has no effect on an organism?
A point mutation, in which one nitrogen base in a codon is substituted for another, may have no effect on an organism. This is true if the base substitution does not change the amino acid that the codon represents, or if the mutation occurs in a non-critical location in the protein so that the protein's structure is not changed significantly and the protein is still able to function.
Mutations that change one or just a few of nucleotides in a gene on a chromosome are called what?
the correct answer is C. a substitution i know this cause i have this book to this question and point mutation is not one of the answer and i found the answer in the book -No its substituton you jack wagon your books wrong
Name two major types of mutations?
Two major types of mutations are point mutations, which involve a change in a single nucleotide base in the DNA sequence, and chromosomal mutations, which involve changes in the structure or number of chromosomes.
What are mutations that occur at a single point?
Such mutations are called point mutation or gene mutation.
Define a genetic mutation and state the types of genetic mutations?
A genetic mutation is a change in the DNA sequence that can affect an organism's traits. The types of genetic mutations include point mutations (substitution, insertion, deletion), frameshift mutations, and chromosomal mutations (deletion, duplication, inversion, translocation).
A mutation that involves a single nucletiode is called an?
point mutation
