5 Questions
Explain the concept of beneficial mutations and their impact on organisms over time.
Beneficial mutations give organisms a selective advantage and tend to be more common over time, leading to evolutionary change.
What is the result of a point mutation and how does it impact the sequence of amino acids?
Point mutations are changes in a single base pair. They may or may not change the sequence of amino acids.
Describe the difference between a gene mutation and a point mutation.
A gene mutation is a change in the amino acid specified by the DNA sequence and often involves more than a single base pair, whereas a point mutation is a change in a single base pair.
What is a silent mutation and how does it affect the amino acid produced?
A silent mutation is a change in base pair that results in no change to the amino acid produced.
Provide an example of a nonsense mutation and explain its impact on the amino acid produced.
An example of a nonsense mutation is the change in base pair that results in a stop codon replacing the amino acid produced. This type of mutation is often lethal.
