Document Summary
***wanting to see what genes are needed for development*** Twins: happens out in nature; species give out to twins that happen naturally, process you are doing within a lab (certain ways of doing so) Let them develop to about 8-16 cells. Pull them apart (divide into 4 cells) & allow them to develop (without damage) 4 main types of cloning: molecular cloning. Making identical molecules; produced by the body (enzmes, proteins, etc. : cellular cloning. Relatively successful in simple twins: nuclear somatic transfer. Using various tissues/mechanisms that the host body uses itself to create various molecules. Use to dna to get them to work properly. Make copies of cells to establish cell lines. Used to make human tissues = skin, heart, etc. 2 or greater cell embryo separated into individual cells re-implantation could result in identical animals fertilization takes place in the lab (first and second divisions)
