Saturated fatty acids (SAFA)
Fatty acids containing fully saturated alkyl chains (on a molecule). This means that the carbon atoms comprising the chains are held together by one carbon-to-carbon bond and not two or three. High levels of dietary SAFA have been related to increased coronary heart disease (CHD) in humans. Beef fat typically contains approximately 54% saturated fatty…

Satellite DNA
Many tandem repeats (identical or related) of a short basic repeating unit (in the DNA molecule).

Salting out
A technique used for forcing (dissolved) proteins out of a solution by increasing the concentration of salt in the solution. The Na+ and CI- ions derived from the salt compete for and “tie up” water molecules that are solubilizing the protein molecules thereby rendering them insoluble or more insoluble. A method of separating a specific protein…

SI Nuclease
An enzyme that specifically degrades (destroys) single-stranded sequences of DNA.

Rpslk gene
A gene that confers to any soybean plant (possessing that gene in its DNA) resistance to as many as twenty-one strains/races of phytophthora root rot (PRR) disease.
-
Rpslc gene
A gene that confers to any soybean plant (possessing that gene in its DNA) resistance to several strains/races of phytophthora root rot (PRR) disease.
-
Rps6 gene
A gene that confers to any soybean plant (possessing that gene in its DNA) resistance to some strains/races of phytophthora root rot (PRR) disease.

RNA vectors
An RNA (ribonucleic acid) vehicle for transferring genetic information from one cell to another.
-
RNA polymerase
An enzyme that catalyzes the synthesis of a complementary mRNA (messenger RNA) molecule from a DNA (deoxyribonucleic acid) template in the presence of a mixture of the four ribonucleotides (ATP, UTP, GTP, and CTP). Also called transcriptase.

Ricin
A lethal protein naturally produced in castor beans. In 1994, Robert J. Ferl and Paul C. Sehnke genetically engineered the tobacco plant to produce ricin. Attached to a pharmaceutical “guided missile” such as a monoclonal antibody or the CD4 protein, ricin is potentially useful for treatment against some tumors and has been investigated as a…
