A process that takes place in the nucleus of a dividing cell. Mitosis involves the doubling and separation of genetic material and results in the formation of two new nuclei, which each have the same number of chromosomes as the parent nucleus.
genome
A complete set of the genes in one organism.
alleles
Any of the alternative forms of a gene that may occur at the same place on a chromosome, for example, the genes responsible for blood type that are found on chromosome 9.
polymerase chain reaction (PCR)
A laboratory technique for amplifying DNA in-vitro. Uses a thermocycler, primers, DNA polymerase, and nucleotides.
heterozygous
Having two different alleles at one location on two homologous chromosomes.
karyotype
A image of the chromosome pairs of a cell arranged by size and shape.
centromere
The centralized region joining two sister chromatids.
Familial Hypercholesterolemia
An autosomal, dominant genetic disorder that disrupts the body's ability to eliminate low-density lipoprotein (LDL) from the blood, resulting in an increased risk of heart attack.
metastasis
The spread of cancerous cells to other tissues or parts of the body.
genotype
All or part of the genetic constitution of an individual or group.
