Transgenic are genetically modified WITH ANOTHER ORGANISM’s DNA Genetically Modified Organism genes WITHIN THAT ORGANISM have been modified…..NOT Dangerous at all……..all about BREEDING. gene therapy Technique for replacing a faulty gene with a normal one in people with fatal or extremely debilitating genetic diseases. Oligonucleotides block Transcription and Translation of a specific DNA site. They bypass the gene & protein problem altogether. makes larger DNA/RNA pieces easier to analyze; vary in length from 2-200 bp; most common are 20-30 bp. Antisense Drugs nontoxic; safe; and retard bad protein synthesis gene mapping The process of delineating the relative order & positions of genes on the chromosomes of living things. Károly Ereky a Hungarian agricultural engineer, first uses the word biotechnology Alexander Fleming notices that a certain mold could stop the duplication of bacteria, leading to the first antibiotic: penicillin restriction enzymes enzymes that clip; "restrict" the entry of foreign DNA into the cells. genetic marker help locate specific sites along a DNA strand; thus useful in preparation of gene maps/DNA profiles. ligase seal the sticky ends together by rejoining the phosphate-sugar bonds; it splices genes into plasmids & chromosomes. reverse transcriptase enzyme that converts RNA into DNA; copies called copy DNA (cDNA) can be made from mRNA/tRNA/rRNA/& other RNA forms. electric current flow from a negative pole to the positive pole causing DNA pieces to migrate in the gel substrate toward the positive pole. DNA Relative sizes denoted by the # of base pairs (bp) hybrid offspring that arises from the union of 2 genetically different parents. gene probes oligonucleotide tracers hybridization can detect specific nucleotide sequences in unknown samples. Southern Blot separates fragments of DNA using electrophoresis and identifies them by hybridization. Dot blot simple/rapid; does not require electrophoresis; DNA is isolated, denatured, and placed on absorbent filter. Then combined w/a microbe-specific probe.
