What is an inversion mutation?

Back

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

What is a chromosomal mutation?

Back

A chromosomal mutation involves changes that affect large segments of DNA, including deletions, duplications, inversions, and translocations.

What is a deletion mutation?

Back

A deletion mutation is a type of mutation where a part of a chromosome or a sequence of DNA is lost.

Front

What is nondisjunction?

Back

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division, leading to gametes with an abnormal number of chromosomes.

Front

What is Down Syndrome?

Back

Down Syndrome, also known as Trisomy 21, is a genetic disorder caused by the presence of an extra chromosome 21, resulting in developmental and physical challenges.

Front

What is a point mutation?

Back

A point mutation is a change in a single nucleotide in the DNA sequence, which can lead to changes in the amino acid sequence of a protein.

Front

What is Sickle Cell Anemia?

Back

Sickle Cell Anemia is a genetic disorder caused by a point mutation in the hemoglobin gene, leading to abnormal red blood cell shapes and function.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are inserted or deleted from the DNA sequence, altering the reading frame of the gene.

Front

What is translocation in genetics?

Back

Translocation is a mutation where a segment of one chromosome breaks off and attaches to another chromosome.
