A.
To determine: Whether insertion of a single
Concept introduction: Mutations are variations in codons caused by changes in nucleotides at or near the coding sequence. Some variations do not have much effect, as the genetic code is degenerate. These are silent mutations. However, some mutations can have an effect on cellular functions due to altered protein synthesis.
B.
To determine: Whether removal of a single nucleotide near the beginning of the coding sequence harms an organism.
Concept introduction: Mutations are variations in codons caused by changes in nucleotides at or near the coding sequence. Some variations do not have much effect, as the genetic code is degenerate. These are silent mutations. However, some mutations can have an effect on cellular functions due to altered protein synthesis.
C.
To determine: Whether deletion of three consecutive nucleotides in the middle of the coding sequence harms an organism.
Concept introduction: Mutations are variations in codons caused by changes in nucleotides at or near the coding sequence. Some variations do not have much effect, as the genetic code is degenerate. These are silent mutations. However, some mutations can have an effect on cellular functions due to altered protein synthesis.
D.
To determine: Whether deletion of four consecutive nucleotides in the middle of the coding sequence harms an organism.
Concept introduction: Mutations are variations in codons caused by changes in nucleotides at or near the coding sequence. Some variations do not have much effect, as the genetic code is degenerate. These are silent mutations. However, some mutations can have an effect on cellular functions due to altered protein synthesis.
E.
To determine: Whether substitution of one nucleotide for another in the middle of the coding sequence harms an organism.
Concept introduction: Mutations are variations in codons caused by changes in nucleotides at or near the coding sequence. Some variations do not have much effect, as the genetic code is degenerate. These are silent mutations. However, some mutations can have an effect on cellular functions due to altered protein synthesis.
