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 lead to changes in the structure and function of proteins.

Front

What are the types of DNA mutations?

Back

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

Front

What is a substitution mutation?

Back

A substitution mutation occurs when one nucleotide is replaced by another, potentially altering the amino acid sequence of a protein.

Front

What is a deletion mutation?

Back

A deletion mutation involves the loss of one or more nucleotides from the DNA sequence.

Front

What is an insertion mutation?

Back

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

Front

What is an inversion mutation?

Back

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

Front

Where do mutations primarily occur?

Back

Mutations primarily occur in DNA.

Front

In DNA, which base pairs with Adenine (A)?

Back

In DNA, Adenine (A) pairs with Thymine (T).

Front

In DNA, which base pairs with Cytosine (C)?

Back

In DNA, Cytosine (C) pairs with Guanine (G).

Front

What is the effect of a mutation on protein synthesis?

Back

Mutations can alter the amino acid sequence of proteins, potentially affecting their function.
