True
|
|
|
False, amino can cause changes to the protein structure
|
|
|
False, sometimes the structure can change without the function changing.
|
|
|
False, amino acids cannot change.

Detailed explanation-1: -A mutation in the amino acid sequence may alter the structure of a protein but it does not necessarily alter its function, although, the mutation at specific sites such as conserved residues can bring about a change in the structure and function of the protein.
Detailed explanation-2: -The unique amino acid sequence of a protein is reflected in its unique folded structure. This structure, in turn, determines the protein’s function. This is why mutations that alter amino acid sequence can affect the function of a protein.
Detailed explanation-3: -Answer and Explanation: The given statement is true.
Detailed explanation-4: -Amino acid replacement is a change from one amino acid to a different amino acid in a protein due to point mutation in the corresponding DNA sequence. It is caused by nonsynonymous missense mutation which changes the codon sequence to code other amino acid instead of the original.
