Mutations

Front

What are mutations?

Back

Mutations are changes in the DNA sequence of an organism's genome, which can lead to changes in the organism's traits.

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 of the genetic code.

Front

Why are insertion and deletion mutations harmful?

Back

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

Front

What is a point mutation?

Back

A point mutation is a change in a single nucleotide in the DNA sequence, which can result in a different amino acid being produced.

Front

What is base substitution?

Back

Base substitution is a type of point mutation where one nucleotide is replaced by another, potentially altering the amino acid sequence.

Front

What is the role of adenine in DNA?

Back

Adenine is one of the four nucleotide bases in DNA and it pairs with thymine.

Front

What is the significance of mutations in evolution?

Back

Mutations create genetic diversity, which is essential for evolution and adaptation in populations.

Front

What is the difference between insertion and deletion mutations?

Back

Insertion mutations add one or more nucleotides to the DNA sequence, while deletion mutations remove one or more nucleotides.

Front

What is a silent mutation?

Back

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

Front

What is a missense mutation?

Back

A missense mutation is a type of point mutation that results in a different amino acid being incorporated into a protein.
