Bio 1510 Exam 4 1 Natural processes involving genetic recombination of genomes of two different prokaryotic cells include: conjugation, transfection, and transduction. Does not include transposition. For the lac operon found in prokaryotes, lactose binds to the repressor protein, reducing its ability to bind to the operator region of the lac operon. Characteristics of prokaryotic and eukaryotic gene expression – prokaryotes and simple eukaryotes share approximately the same number of “housekeeping” genes (the minimum required for essential life functions); eukaryotes have more regulatory genes in their DNA than prokaryotes. A transposon consists of a functional gene flanked by transposable elements. In eukaryotes, genes can be composed of coding regions called exons , interspersed with non-coding regions, or introns . The genome of the puffer fish, Fugu, compared to the human genome, has about the same number of genes and less total DNA. Methylation within prokaryotic host DNA strands prevent cleavage by host DNA restriction enzymes . Plasmids are: a critical component genetic recombination during conjugation; often used as a vector for generation recombinant genotypes in bacteria; vehicles for introducing useful genes into eukaryotic genomes. A successful vector mush have a
