Mutations

What best describes a change in the DNA sequence?

• Transcription

• Translation

• Mutation

• Replication

What type of mutation involves substituting a DNA base with another base?

• Frameshift

• Point

• Translocation

• Chromosomal

What type of mutation involves substituting a DNA base with a different base but still forms the same protein?

• Nonsense Mutation

• Missense Mutation

• Inversion Mutation

• Silent Mutation

What type of mutation involves adding or deleting bases from the DNA, which results in new codons (a shift in the reading of the codons)?

• Nonsense Mutation

• Frameshift Mutation

• Point Mutation

• Chromosomal Mutation

Original DNA = TAC GAC TTG AAT
