Missence mutation
The sequence of amino acids in cystic fibrosis is caused by a mutation in the CFTR gene, which leads to the production of a faulty cystic fibrosis transmembrane conductance regulator protein. This mutated protein results in abnormal function, leading to the characteristic symptoms of cystic fibrosis such as thick mucus production.
This mutation would cause a frameshift mutation, shifting the reading frame of the DNA sequence. Most likely, this would lead to a completely different protein being translated, resulting in a protein with a different sequence of amino acids from the original protein. The number of amino acids would depend on the specific changes in the protein sequence caused by the frameshift mutation.
A frame shift mutation destroys the correct sequence of amino acids from the point of the mutation. The protein produced by a frame shift mutation would more than likely be nonfunctional.
In a point mutation, a change in a single nucleotide can lead to a specific mutation. For example, a substitution mutation occurs when one nucleotide is swapped for another, such as A to T or C to G. This change can result in different amino acids being coded for in the protein sequence.

Mutation occurs in the DNA of the cell. Mutation leads to changes in the sequence of amino acids in a protein. Altered protein function affects the traits expressed by the cell.
Aminoaciduria-- The abnormal presence of amino acids in the urine.Primary or overflow aminoaciduria results from deficiencies in the enzymes necessary to metabolize amino acids.
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.
It is possible for a point mutation to not change the sequence of amino acids in a protein. This will result in the protein being unchanged and will not affect the phenotype.
A frameshift mutation, where nucleotides are removed from a gene, can change the reading frame of the gene. This alters the sequence of amino acids in the resulting protein, leading to a non-functional or abnormal protein. This can have serious consequences on the protein's structure and function, potentially causing genetic disorders or diseases.
In a point mutation, a change in a single nucleotide can lead to a specific mutation. For example, a substitution mutation occurs when one nucleotide is swapped for another, such as A to T or C to G. This change can result in different amino acids being coded for in the protein sequence.
dna in a cell needs protein and chromosomes.
A frameshift mutation, such as an insertion of one nucleotide, is most likely to produce a protein with one extra amino acid. This type of mutation shifts the reading frame of the genetic code, leading to a change in the entire sequence of amino acids after the mutation site.
