Yes, a point mutation can result in a frameshift mutation if it occurs in a coding region of a gene and disrupts the reading frame of the genetic code.
A point mutation is not a frameshift mutation. Point mutations involve changes in a single nucleotide base, while frameshift mutations involve the insertion or deletion of nucleotide bases, causing a shift in the reading frame of the genetic code.
A frameshift mutation, where an insertion or deletion of nucleotides causes a shift in the reading frame of the genetic code, can change every amino acid that follows the point of mutation. This can have dramatic effects on the resulting protein's structure and function.
No
SCID can be caused by a variety of genetic mutations, including both frameshift and point mutations. Frameshift mutations involve the insertion or deletion of nucleotides that shifts the reading frame of a gene, while point mutations involve the substitution of a single nucleotide.

A point mutation is not a frameshift mutation. Point mutations involve changes in a single nucleotide base, while frameshift mutations involve the insertion or deletion of nucleotide bases, causing a shift in the reading frame of the genetic code.
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.
A frameshift mutation, where an insertion or deletion of nucleotides causes a shift in the reading frame of the genetic code, can change every amino acid that follows the point of mutation. This can have dramatic effects on the resulting protein's structure and function.
No
frameshift mutation, which alters the reading frame of the gene. This can result in a nonfunctional or altered protein being produced.
SCID can be caused by a variety of genetic mutations, including both frameshift and point mutations. Frameshift mutations involve the insertion or deletion of nucleotides that shifts the reading frame of a gene, while point mutations involve the substitution of a single nucleotide.
From another angle: beneficial and detrimental.
A frameshift mutation
A point mutation is never a frameshift mutation because it involves the substitution of a single nucleotide for another rather than the insertion or deletion of nucleotides that would disrupt the reading frame of a gene.
PKU (phenylketonuria) is a point mutation, specifically an autosomal recessive genetic disorder caused by a mutation in the PAH gene. This mutation leads to impaired metabolism of the amino acid phenylalanine. It is not a frameshift mutation, which would involve an insertion or deletion of nucleotides, shifting the reading frame of the gene.
A mutation in which an extra nitrogen base is added is called a frameshift mutation. The rest of the sequence after the mutation will code for different amino acids, which will result in the alteration of the protein. Frameshift mutations cause severe genetic disorders.
