Mutations

What is a frameshift mutation?

• A mutation that shifts the "reading" frame of the genetic message by inserting or deleting nucleotides.

• A mutation that changes a single nucleotide but does not affect the reading frame.

• A mutation that reverses the direction in which a gene is read.

• A mutation that occurs in non-coding regions of DNA.

Identify the following mutation:
Original DNA: ATCGTC
Mutated DNA: AATCGTC

• Substitution
• Insertion
• Deletion

A mutation in which only one nucleotide is altered is called a:

• Frameshift Mutation

• Deletion Mutation

• Point Mutation

• Insertion Mutation

The information encoded in DNA is transcribed to mRNA using:

• DNA Polymerase

• RNA Polymerase

• Ribosomes

• Helicase
