A point mutation causes a change in the amino acid sequence creating a new type of protein. The mutations are categorized functionally as nonsense, missense and silent mutations.

∙ 6y agoIf a substitution changes the amino acid to a "stop," it's called a NONSENSE mutation. frame shift, missense, silent or nonsense (hint: deletion or insertion will always be frame shift). Sickel cell anemia is the result of a type of mutation in the gene that codes for part of the hemoglobin molecule.

What is a Missence mutation?
A mutation that causes the code for the wrong amino acid (apexvs.com)
Which type of mutation results in the formation of a protein with one incorrect amino acid-?
Missense is a type of mutation which results in the formation of a protein with one incorrect amino acid.
What amino acid is coded for by this sequence before the mutation?
The neutral mutation does not change the amino acid coded for by the codon. A good example is the RNA codon that could be the CCA, CCC or the CCG.
What can occur as a result of a change in the sequence of nucleotides in a strand of DNA?
The addition or deletion of a nucleotide can lead to a Frameshift mutation. The Frameshift mutation causes a "shift" in the reading frame of the codons in the mRNA. This may lead to the change in the amino acid sequence at protein translation.
What produces a nonsense mutation?
A nonsense mutation is a genetic mutation in a DNA sequence that leads to the appearance of a stop codon where previously there was a codon specifying an amino acid. DNA is a chain of many smaller molecules called nucleotides. During protein formation, DNA (or RNA) nucleotide sequences are read three nucleotides at a time in units called codons, and each codon corresponds to a specific amino acid or stop codon, which is also called nonsense codon because it does not code for an amino acid and instead signals the end of protein synthesis. Therefore, nonsense mutations occur when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, this premature stop codon results in the production of a shortened, and likely nonfunctional, protein.

A mutation is a change in DNA sequence and?
Amino acid order.
What is a A genetic mutation that does not result in a change in the amino acid sequence of the resulting protein is called?
a silent mutation.
What is a chromosomal mutation?
mutation is a permanent change in the DNA sequence of a gene and can alter the amino acid sequence of the protein encoded by the gene..
When a nitrogenous base is inserted or delete how does that affect the amino acid sequence?
The amino acid sequence is shifted, and this kind of mutation is called a frame shift mutation. All of the amino acid sequence after the mutation will be changed, which will cause a change in shape of the protein, which will then probably result in a nonfunctional protein, since the shape of a protein determines its function.
Which type of mutation results in the formation of a protein with one incorrect amino acid-?
Missense is a type of mutation which results in the formation of a protein with one incorrect amino acid.
What impact could a point mutation do?
A point mutation could have no impact or it could be lethal. It depends on whether the mutation changes the amino acid sequence of a protein, or if it changes the amino acid at a critical location in the protein.
What amino acid is coded for by this sequence before mutation?
The neutral mutation does not change the amino acid coded for by the codon. A good example is the RNA codon that could be the CCA, CCC or the CCG.
What amino acid is coded for by this sequence before the mutation?
The neutral mutation does not change the amino acid coded for by the codon. A good example is the RNA codon that could be the CCA, CCC or the CCG.
What would be the effect of a mutation that changed the c of the anticodon to a g?
The effect of the mutation is; there would be another amino acid that may form due to the change in sequence of the anticodon. change in the sequence of anticodon may result to different amino acid that may form.
