DNA Mutations Review

Front

What is a DNA mutation?

Back

A DNA mutation is a change in the nucleotide sequence of the DNA, which can affect genetic information.

Front

What are the types of DNA mutations?

Back

The main types of DNA mutations are substitution, insertion, deletion, and inversion.

Front

Define substitution mutation.

Back

A substitution mutation is when one base pair in the DNA sequence is replaced by another base pair.

Front

What is a deletion mutation?

Back

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

Front

What is an insertion mutation?

Back

An insertion mutation involves the addition of one or more nucleotide pairs into the DNA sequence.

Front

What is an inversion mutation?

Back

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

Front

What base pairs pair with Adenine (A) in DNA?

Back

Thymine (T) pairs with Adenine (A) in DNA.

Front

What base pairs pair with Cytosine (C) in DNA?

Back

Guanine (G) pairs with Cytosine (C) in DNA.

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.

Front

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

Back

A substitution mutation can lead to a change in one amino acid in the protein, potentially altering its function.
