Exploring Genetic Mutations and Effects

Front

What is an operon?

Back

A group of related genes and the associated gene switches in prokaryotes.

Front

What is a frameshift mutation?

Back

A mutation that shifts the reading frame of the genetic message.

Front

In which organisms are operons found?

Back

Bacteria (prokaryotes).

Front

What happens to the reading frame of a gene during a frameshift mutation?

Back

It shifts by one or more nucleotides.

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to changes in gene function.

Front

What are the two main types of mutations?

Back

Point mutations and frameshift mutations.

Front

What is a point mutation?

Back

A mutation that changes a single nucleotide in the DNA sequence.

Front

What is the effect of a silent mutation?

Back

It does not change the amino acid sequence of the protein.

Front

What is a missense mutation?

Back

A mutation that results in a different amino acid being incorporated into a protein.

Front

What is a nonsense mutation?

Back

A mutation that creates a premature stop codon in the protein sequence.
