WebJan 13, 2024 · The change in the reading frame alters the grouping of the bases and subsequently changes the amino acids that are encoded. Often, the encoded protein is non-functional. A visual depiction of a frameshift mutation. What is a duplication mutation? In the case of a duplication mutation, a piece of DNA is (abnormally) copied. WebOct 4, 2024 · A deletion mutation is the opposite; it occurs when a base pair is deleted from a sequence. These two types of point mutations are grouped together because both of them can drastically affect the sequence of amino acids produced. With one or two bases added or deleted, all of the three-base codons change. This is called a frameshift mutation.

How does a frame-shift mutation affect the translated protein?

WebThe outcome of a frameshift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA … WebOct 28, 2024 · The insertion changes drastically the nature of the proteins produced by the DNA chain. Insertion mutations cause the production of the wrong amino acids, cause early termination of the amino acid chain (protein), and change highly structured information stored in the DNA to nonsense producing non functional proteins.
