All DNA is recombinant DNA. Genetic exchange works constantly to blend and rearrange chromosomes, most obviously during meiosis, when homologous chromosomes pair prior to the

Cloning vectors: 克隆载体 to clone a gene in a vector Expression vectors: 表达载体 to express a gene from a vector Integration vectors: 整合载体 to integrate a gene in a genome through a vector Cloning vectors 1 Plasmid vecters 2 Bacteriophage vectors 3 Cosmids & BACs 4 Eukaryotic vectors Cloning vectors: allowing the exogenous DNA to be inserted, stored, and manipulated mainly at DNA level. expression vectors: allowing the exogenous DNA to be inserted, stored, and expressed

Automotive Developments 1600-The Dutch employed wind power to propel sail-mounted carriages which raced along at 20 mph and held scores of passengers. It is quite probable that both speed and load capacity were exaggerated. Later, small carriages were equipped with wind-mills, the mill vanes geared to the wheels. These were probably the first land vehicles to be propelled by
