Bacic Answer:
Point mutations occur when a single nucleotode is replaced with another nucleotide tide base. Insertion and come in this category.
More Detail Answer:
Point mutations occur when a single nucleotide is replaced with another nucleotide tide base. Insertion and come in this category. Error in the process of replication of DNA molecule results in point mutations. Sometimes heat of high level radiation cause the error in DNA replication. There are different effects of point mutations. if this type of mutation occurs in the sequence of DNA molecule or exon, then the protein sequence changes present in the gene. If the mutation occurs in the RNA effecting the codon of gene Sickle cell anemia is cause by the point mutations. Changes occur in the beta hemoglobin. it converts GAC sequence into GUG, Point mutation can be subdivided into three types:
1) Nonsense mutations are the ones which code for the same amino acid.
2) Misssense mutations occur in the genes which code for different amino acid.
3)Silent mutations do not affect the function of the protein and code for different of same amino acid.

Point mutations in noncoding regions are often harmless.

Mutations that occur at one single nitrogen base are referred to as?
Mutations that occur at one single nitrogen base are referred to as a point mutation.
A mutation that involves a single nucleotide is called a(an)?
Point Mutation- a type of gene mutation in which only a single nucleotide in a gene has been changed.
Name two major types of mutations?
Frameshift mutations and Point mutations. The difference between the two are that point mutations occur at a single point in the DNA sequence and frameshift mutations shift the "reading frame" of the genetic message.
Can a point mutation be frameshift mutation?
No
Is SCID a frameshift mutation or a point mutation?
point! good luck
What are mutations that occur at a single point?
Such mutations are called point mutation or gene mutation.
Mutations that occur at one single nitrogen base are referred to as?
Mutations that occur at one single nitrogen base are referred to as a point mutation.
A change in a single nucleotide in DNA-?
A mutation

Can a point mutation be frameshift mutation?
No
The substitution addition or removal of a single nucleotide in DNA is called a what mutation?
point mutation
Is SCID a frameshift mutation or a point mutation?
point! good luck
When a child is born chromosomal mutation when did the mutation occur?
During meiosis
When a child is born with a chromosomal mutation when did mutation occur?
during meiosis
Which mutation cannot occur in a tRNA encoding gene?
nonsense mutation
Can a frameshift mutation be a silnt mutation?
A frameshift mutation completely changes the genetic code from the point of the mutation, so the protein made as a result of the mutation would have the incorrect structure and would not function as it should.
