Mutations Practice Flashcard

Front

What is a Nonsense Mutation?

Back

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

Front

What is Translocation in genetics?

Back

A chromosomal mutation where a piece of one chromosome detaches and reattaches to a different chromosome.

Front

Define a Gene.

Back

A segment of DNA that encodes for a protein.

Front

What are Codons?

Back

mRNA sequences read in chunks of three nucleotides, each coding for a specific amino acid.

Front

What is Duplication in genetics?

Back

A mutation where a piece of a chromosome is copied and remains within the chromosome.

Front

What is a Missense Mutation?

Back

A type of substitution mutation that results in a different amino acid being incorporated into a protein.

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 a Deletion Mutation?

Back

A mutation where a segment of DNA is removed, potentially leading to a frameshift in the reading frame.

Front

What is a Chromosome?

Back

A structure made of DNA and proteins that contains genetic information.

Front

What is the role of mRNA?

Back

To carry genetic information from DNA to the ribosome, where proteins are synthesized.
