Matching

Match each term with the appropriate definition.

Premises:

Responses:

nutrigenomics

heritable changes in gene function that do not entail a change in the DNA sequence

chromosomes

structures in the nuclei of cells that contain genes

gene variant

segments of genes that provide instructions for the synthesis, or production, of specific enzymes and other proteins needed by cells to carry out life- and health-sustaining processes

hemochromatosis

a rare genetic disorder caused by a lack of enzyme phenylalanine hydroxylase

phenylketonuria

basic units of heredity that occupy specific places (loci) on chromosomes

deoxyribonucleic acid

the specific genetic makeup of an individual as coded by DNA

sitosterolemia

study of the functions and interactions of all genes in the genome

epigenetic

a single-gene defect disorder that interferes with the body's utilization of the sugar galactose found in lactose

genotype

represents all the genes and DNA contained in an organism

genomics

occurs because of a defect in a gene that produces a protein that controls how much iron is absorbed from food

nucleotide

a different form of a gene that has a different functional status than the original gene

galactosemia

disorders resulting from one abnormal gene

single-gene defects

A rare disorder caused by a mutation in one of two genes that affect the ability of small intestine cells to dispose of plant sterols in the feces
