What is it called when a point substitution mutation has no effect?

• Substitution Mutation

• No Mutation

• Silent Mutation

What is a mutation?

• A change in a chromosomal region.

• A negative change in the nucleotide sequence of DNA.

• A change in one base pair in DNA.

• Any change in the nucleotide sequence of DNA.

Given this DNA Sequence:

TAC TAG CCG AGT

What is the correct amino acid sequence?

Match the following Mutations

• Only one nucleotide is affected

• Substitution

• More than one nucleotide is affected and entire sequence shifts

• Frameshift

• One Nucleotide is swapped for another

• Insertion

• Entire sequence shifts to the left

• Point

• Entire sequence shifts to the right

• Deletion

Match the following Mutations

• Has no effect on amino acids or proteins

• Missense

• Causes chance in amino acid sequence ; results in different protein

• Silent

• Causes an amino acid to change into a "STOP" codon

• Nonsense
