Practical 1: Observation of mitosis in garlic root tips Introduction The practical will involve the preparation‚ observation‚ and classification‚ of the various stages of mitosis by observing garlic root tips using a microscope. The study comes under the heading of cytogenetics which is the visual characterisation of genetic material and the study of how that material reacts during the life of the cell. Strictly speaking‚ mitosis is the division of the nucleus into two daughter nuclei that are

The purpose of module E is to learn several DNA techniques in the lab including DNA purification with solubility and absorption‚ plasmid transfection of E.coli‚ colony screening by PCR and quantitative PCR. First part of the experiment E1 show the purification method of DNA through solubility. E. coli lysate mixed organic solvents to purify the DNA present in solution. First‚ the lysate was mixed with phenol/chloroform‚ then vortexed‚ and centrifuged. We extracted the aqueous layer and combined

Victor Seo Toronto University ABSTRACT It is often said that eating chocolate will give you acne. To further this idea‚ 400 students from high schools are divided into 4 groups and each group is given different amounts of chocolate daily (1 bar‚ 3 bars‚ 6 bars‚ or 10 bars). They are treated for a month until the observation is finished. After testing them‚ data shows that there is a weak positive correlation between eating chocolate and having acnes. In brief‚ chocolate is not a cause of

Also‚ to transform E.coli DH5α cells by introducing the plasmids DNA which contains the gene of interests into the E.coli strain(DH5α). The plasmid DNA can replicate inside the transformed E.coli DH5α cells‚ only successful transformed cells can produce the protein that is resistance to kanamycin‚ this allows for the selection of successful transformed cells. 2.
