Answer
Point mutations can significantly affect the structure and function of a protein.
Solution
a
Point mutations: These are changes in a single nucleotide base in the DNA sequence. They can be classified into different types such as silent, missense, and nonsense mutations
b
Missense mutations: These result in the substitution of one amino acid for another in the protein sequence. This can lead to changes in the protein's folding and stability
c
Protein folding: The specific sequence of amino acids determines how a protein folds into its three-dimensional structure. A change in one amino acid can disrupt this folding, potentially leading to a non-functional protein
Key Concept
Point mutations can alter the amino acid sequence of a protein, affecting its folding and function.
Explanation
A point mutation that changes an amino acid in the protein sequence can disrupt the protein's normal folding, leading to a loss of function or gain of a new, potentially harmful function.
