DNA Mutations

Front

In DNA, A goes with __ and C goes with __

Back

A pairs with T (Thymine) and C pairs with G (Guanine).

Front

Identify the type of mutation when one base is replaced by another in a DNA sequence.

Back

This is called a substitution mutation.

Front

What is an insertion mutation?

Back

An insertion mutation occurs when one or more nucleotide bases are added to a DNA sequence.

Front

What is a deletion mutation?

Back

A deletion mutation occurs when one or more nucleotide bases are removed from a DNA sequence.

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 translocation mutation?

Back

A translocation mutation occurs when a segment of DNA is moved from one location to another within the genome.

Front

What is an inversion mutation?

Back

An inversion mutation occurs when a segment of DNA is reversed end to end.

Front

What is the difference between a point mutation and a frameshift mutation?

Back

A point mutation involves a change in a single nucleotide, while a frameshift mutation involves the insertion or deletion of nucleotides that shifts the reading frame.

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the significance of mutations in evolution?

Back

Mutations introduce genetic variation, which can lead to new traits that may be beneficial for survival and reproduction.
