the activation of a gene that results in the formation and production of mRNA
the complete genetic material contained in an individual
genes that code for polypeptides
a DNA segment that serves as a kind of "switch" by controlling the access of RNA polymerase to the promoter
a series of genes that code for specific products and the regulatory elements that control these genes
a gene system whose operator gene and three structural genes control lactose metabolism in E. coli
a protein that inhibits genes from being expressed
a regulatory protein that binds to an operator an dblocks transcription of the gene of an operator
a molecule that initiates gene expression
the site of active transcription of DNA to RNA a region of DNA that is uncoiled and undergoing active transcription into RNA
a segment of a structural gene that is transcribed but not translated
sequence of nucleotides on a gene that gets transcribed and translated
form of messenger RNA that contains both introns and extrons
regulatory proteins in eukaryotes that binds to DNA and stimulates the transcription of certian genes
a DNA sequence that recognizes certain transcription factors that can stimulate transcription of nearby genes
the process by which a cell becomes specialized for a specific structure or function
a gene that controls the development of a specific adult structure
a DNA sequence within a homeotic gene that regulates development in animals
A gene that regulates normal cell division but that can become a cancer causing oncogene as a result of mutation or recombination
a gene that induces cancer, or uncontrolled cell proliferation
a growth that arises from normal tissue but that grows abnormally in rate and structure and lacks a function
a tumor in which the cells begin dividing at an uncontrolled rate and become invasive
Tumor- Suppressor Gene
a gene that suppresses tumor formation but that, when mutated, causes a loss in cell function, which results in tumor formation
the spread of cancer cells beyond their original site of growth
a cancer-causing substance
a malignant tumor that grows in the skin or in the tissues that line organs
a malignant tumor that grows in bone or muscle tissue
a tumor in the lymphoid tissues
a progressive, malignant disease of the blood-forming organs
