Question
A point mutation can result in which of the following?Group of answer choicesan incomplete proteinan abnormal proteinno effect on the proteinany of thesenone of these
Solution
A point mutation can result in any of the following:
-
An incomplete protein: If the point mutation results in a premature stop codon, the protein synthesis can stop prematurely, leading to an incomplete protein.
-
An abnormal protein: If the point mutation changes the amino acid sequence, it can lead to a protein with a different structure and potentially different function, which can be considered abnormal.
-
No effect on the protein: If the point mutation is a silent mutation, it does not change the amino acid sequence of the protein. Therefore, the structure and function of the protein remain the same.
-
Any of these: As explained above, a point mutation can lead to an incomplete protein, an abnormal protein, or have no effect on the protein.
-
None of these: This option is not correct because a point mutation can indeed lead to any of the outcomes listed above.
