Bio Unit 8: Q2 Up to Mutations 2024 Short

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence.

Front

What type of mutation occurs when one base is replaced by another?

Back

Substitution.

Front

What mutation would cause a protein to be shorter than normal?

Back

Stop Codon Found.

Front

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

Back

Insertions and Deletions.

Front

What happens during an inversion mutation?

Back

Part of the chromosome is attached backwards.

Front

What is an insertion mutation?

Back

An insertion mutation occurs when one or more bases are added to the DNA sequence.

Front

What is a deletion mutation?

Back

A deletion mutation occurs when one or more bases are removed from the DNA sequence.

Front

What is the effect of a frameshift mutation on protein synthesis?

Back

It alters the reading frame, potentially changing all subsequent amino acids.

Front

What is a stop codon?

Back

A stop codon is a nucleotide triplet that signals the end of protein synthesis.

Front

What is the difference between a point mutation and a frameshift mutation?

Back

A point mutation changes one base pair, while a frameshift mutation alters the entire reading frame.
