What happens if the sequence of amino acids is changed?

The change can cause the wrong amino acid to be produced. In some cases, the change has little effect. In other cases, the incorrect amino acid can affect the structure or function of the protein being encoded.

What type of mutation causes a change in the amino acid sequence?

Missense mutation: changes an amino acid to another amino acid.

Can mutations affect amino acid sequences?

Some mutations do not result in changes in the amino acid sequence of the encoded protein and can be described as silent mutations. Other mutations result in abnormal protein products. Mutations can introduce new alleles into a population of organisms and increase the population’s genetic variation.

What happens if the sequence is changed mutations protein synthesis?

Consequently, once it encounters the mutation, the ribosome will read the mRNA sequence differently, which can result in the production of an entirely different sequence of amino acids in the growing polypeptide chain.

How mutations may cause changes in the structure and function of a protein?

Sometimes, gene variants (also known as mutations) prevent one or more proteins from working properly. By changing a gene’s instructions for making a protein, a variant can cause a protein to malfunction or to not be produced at all.

How do frameshift mutations change the amino acid sequence?

In biology, insertions or deletions of nucleotides in the coding region resulting in an altered sequence of amino acids at the translation of the codons are known as frameshift mutations. This type of mutation may result in phenotypic changes, for instance, the production of an altered protein.

Which of the following mutation types may change codons downstream of the mutation?

Explanation: A frameshift mutation indicates that the reading frame of the sequence in altered, resulting in production of different codons downstream of the mutation.
