Question

question 8 of 10
which of the following produces no change in a phenotype?
a. transformation
b. point mutation
c. silent mutation
d. dna rearrangement

Explanation:

• Transformation: involves the uptake of foreign genetic material, which can change the phenotype.
• Point mutation: a single - base change. It can lead to a change in the amino acid sequence (if it is a missense mutation) or a stop codon (nonsense mutation), both of which can change the phenotype.
• Silent mutation: a change in the DNA sequence that does not result in a change in the amino acid sequence of the protein (due to the degeneracy of the genetic code). Since the protein remains the same, there is no change in the phenotype.
• DNA rearrangement: can disrupt gene function or create new gene fusions, which can change the phenotype.

Answer:

C. Silent mutation
