Translocation

Translocation means a change in location. It usually refers to genetics, when part of a chromosome is transferred to another chromosome. Chromosomes are structures that carry genes, our units of heredity. When this type of translocation occurs, it can cause flaws in chromosomes.

In another type of translocation, two chromosomes trade pieces with each other.

Genetic translocations can cause serious disorders, including a type of leukemia.

Chromosomes and DNA

Humans typically have 23 pairs of chromosomes, or 46 chromosomes in total. Chromosomes are made up of long strands of DNA, which contain all the body's genes.
