Mutations

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism's genome.

Front

What are the main types of mutations?

Back

The main types of mutations include point mutations, frameshift mutations, and large-scale mutations.

Front

What is a point mutation?

Back

A point mutation is a change in a single nucleotide in the DNA sequence.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are inserted or deleted from the DNA sequence, altering the reading frame.

Front

What is a deletion mutation?

Back

A deletion mutation is a type of frameshift mutation where one or more nucleotides are removed from the DNA sequence.

Front

What is a nonsense mutation?

Back

A nonsense mutation is a mutation that creates an early stop codon in the protein sequence, leading to a truncated protein.

Front

What is a silent mutation?

Back

A silent mutation is a mutation that does not change the amino acid sequence of a protein.

Front

What is a missense mutation?

Back

A missense mutation is a mutation that results in the substitution of one amino acid for another in a protein.

Front

How do mutations affect protein function?

Back

Mutations can affect protein function by altering the amino acid sequence, potentially changing the protein's structure and function.

Front

What is the significance of early stop codons?

Back

Early stop codons can lead to nonfunctional proteins, which can have significant effects on an organism's phenotype.
