Mutations

Front

What is a Deletion Mutation - Chromosomal?

Back

A type of mutation where a part of a chromosome is deleted, resulting in a loss of genetic material.

Front

What is a Substitution Mutation?

Back

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

Front

What is a Missense Mutation?

Back

A type of mutation that results in a change in one amino acid in a protein, which can affect its function.

Front

What is a Chromosomal Mutation?

Back

Mutations that involve changes to the structure or number of chromosomes, affecting large segments of DNA.

Front

What is Nondisjunction?

Back

The failure of homologous chromosomes to separate during meiosis, leading to gametes with an abnormal number of chromosomes.

Front

What is a Point Mutation?

Back

A mutation that affects a single nucleotide in the DNA sequence.

Front

What is a Silent Mutation?

Back

A mutation that does not change the amino acid sequence of a protein, often occurring in non-coding regions.

Front

What is an Inversion Mutation?

Back

A mutation where a segment of DNA is reversed within the chromosome, potentially disrupting gene function.

Front

What is Translocation?

Back

A chromosomal mutation where a segment of one chromosome breaks off and attaches to another chromosome.

Front

What is a Nonsense Mutation?

Back

A mutation that creates a premature stop codon in the protein sequence, leading to a truncated protein.
