What is an insertion mutation?

Back

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

Front

What is a substitution mutation?

Back

A substitution mutation occurs when one base pair in the DNA sequence is replaced with a different base pair.

Front

What is a deletion mutation?

Back

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

Front

What is a frameshift mutation?

Back

A frameshift mutation is caused by insertions or deletions that change the reading frame of the genetic code.

What is the role of guanine in DNA?

Back

Guanine is one of the four main nucleobases in DNA and pairs with cytosine.

Front

What is the base pairing rule in DNA?

Back

In DNA, adenine pairs with thymine, and guanine pairs with cytosine.

What is a base substitution mutation?

Back

A base substitution mutation is a type of mutation where one base pair is replaced by another base pair.

Front

What is a base insertion mutation?

Back

A base insertion mutation is a type of mutation where an extra base pair is added to the DNA sequence.

What is a base inversion mutation?

Back

A base inversion mutation occurs when a segment of DNA is reversed within the chromosome.
