Front

What is a mutation?

Back

A mutation is a change in the DNA sequence.

Front

What are the types of mutations that can cause a frameshift?

Back

Insertions and Deletions.

Front

Why are frameshift mutations particularly harmful?

Back

They change all of the codons from the mutation on down the line, which changes the amino acid sequence.

Front

What type of mutation is represented by the change from ATTTGAGCC to ATTGAGCC?

Back

Deletion - Frameshift.

Front

What type of mutation occurs when T-G-A-C-C-A changes to T-G-A-G-C-A?

Back

Substitution.

Front

What is the effect of a substitution mutation?

Back

It replaces one nucleotide with another, potentially changing one amino acid in a protein.

Front

What is the difference between insertion and deletion mutations?

Back

Insertion adds one or more nucleotides, while deletion removes one or more nucleotides.

Front

How can mutations affect protein synthesis?

Back

Mutations can alter the amino acid sequence, potentially affecting the protein's function.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides that corresponds to a specific amino acid.

Front

What is the role of DNA in mutations?

Back

DNA contains the genetic information, and mutations are changes in this sequence.
