Document Summary
Chromosomes: structures within the nucleus of a cell made of dna and associated proteins. Epigenetics: the study of heritable changes in gene function that occur w/o a change in the dna sequence. Gene expression: the process by which a cell converts the genetic code into rna and protein. Genes: sections of chromosomes that contain the instructions needed to make one or more proteins. Genomics: the study of all the genes in an organism and their interactions with environmental factors. Human genome: the complete set of genetic material (dna) in a human. Microarray technology: research tools that analyze the expression of thousands of genes simulteously and search for particular genes changes associated with a disease. Mutations: permanent changes in the dna that can be inherited. Nucleotide bases: the nitrogen containing building blocks of dna and rna. Nucleotides: the subunits of dna and rna molecules, composed of a phosphate group. Nutritional genomics: the science of how nutrients affect the activities of genes.
