DNA Mutations (WSHS)

Front

What is a nonsense mutation?

Back

A type of substitution mutation that results in a premature stop codon, leading to a truncated protein.

Front

What is a frameshift mutation?

Back

A mutation that occurs when nucleotides are inserted or deleted from the DNA sequence, causing a shift in the reading frame.

Front

What types of mutations can cause a frameshift?

Back

Both insertions and deletions can cause frameshift mutations.

Front

What is an insertion mutation?

Back

A mutation where one or more nucleotides are added to the DNA sequence.

Front

What is a substitution mutation?

Back

A mutation where one nucleotide is replaced by another, potentially altering the amino acid sequence.

Front

What is a silent mutation?

Back

A mutation that does not change the amino acid sequence of a protein due to redundancy in the genetic code.

Front

What is the impact of a missense mutation?

Back

A missense mutation results in a change in one amino acid in the protein, which may affect its function.

Front

How does a deletion mutation affect the DNA sequence?

Back

A deletion mutation removes one or more nucleotides from the DNA sequence, potentially leading to a frameshift.

Front

What is the genetic code?

Back

The set of rules by which information encoded in genetic material is translated into proteins.

Front

What is the role of codons in DNA?

Back

Codons are sequences of three nucleotides that correspond to specific amino acids or stop signals during protein synthesis.
