Glossary

A simplified diagram of a family's genealogy that shows family members' relationships to each other and how a particular trait or disease has been inherited.

Polyetheretherketone

Polyester Elastomer

Review of project related documents, equipment or construction by industry knowledgeable personnel who are not directly associated with the project.

Polyethylene Glycol

The process of attaching polyethylene glycol (PEG) to molecules to improve the pharmacokinetics and pharmacodynamics of pharmaceuticals, especially for protein and peptide therapeutics.

Polyetherimide

Proton Exchange Membrane

Polyethylene Naphtalate

The percentage of individuals in population that show a particular phenotype among those capable of showing it, i.e., among those that have the genotype normally associated with that phenotype.

The probability of a gene or genetic trait being expressed. “Complete” penetrance means the gene or genes for a trait are expressed in all the population who have the genes. “Incomplete” penetrance means the genetic trait is expressed in only part of the population. The percent penetrance also may change with the age range of the population.

An antibiotic containing a ß-lactam ring that inhibits an enzyme responsible for making peptide cross-links in the bacterial cell wall. It is obtained from cultures of the molds Penicillium Notatum or Penicillium Chrysogenum.

The genus of mold causing a zone of inhibition in an agar plate of bacteria. The organism produces natural penicillin.

Polyethylene Oxide

Polyethyloxazoline

A secondary protein derivative defined as “a definitely characterized combination of two or more amino acids (fewer than 40), the carboxyl (COOH) group of one being united with the amino (NH2) group of the other, with the elimination of a molecule of water”. They form a peptide bond.

The carbon-nitrogen chemical bond that links amino acids to form a peptide chain, which is called a protein if it consists of more than 40 amino acids.

A diverse class of hormones that are synthesized and excreted at various sites within the body. Examples include: insulin, relaxin, glucagons, growth hormone, vasopressin, ACTH (Adrenocorticotropic Hormone), endorphins, and encephalins.

A short chain of amino acids that can induce antibodies against a specific infectious agent.

In computing false positives and false negatives, this is the method in which is insisted that the correct amino acids are predicted, which requires that the reading frame is correctly assigned.

In computing false positives and false negatives, this is the method in which is asked that the correct nucleotides are predicted, without checking if the reading frame is correctly assigned.
