The stages of mitosis are shown for the onion root tip and the whitefish blastula. The top three slides show the onion root tip. The first is anaphase where the chromosomes are separating. The second is metaphase where the chromosomes line up on metaphase plate. The third is interphase. The next three pictures are of the whitefish blastula. The first is anaphase where the chromosomes are separating. The second is interphase and the third is telophase.

INTERPHASE

PROPHASE

Methods of transformation Electroporation –Electrical shock makes cell membranes permeable to DNA Calcium Chloride/Heat Shock –Chemically-competent cells uptake after heat shock

Why perform each transformation step? Positive charge of Ca +2 ions shields negative charge of DNA phosphates CH 2 N N H O O OH O P O O O O Ca++
