Exercise 2 The DNA is a very long molecule which is composed of two complementary banks binding to each other by hydrogen bonds. Two pairs of nitrogenous bases make these hydrogen bonds, the first pair is composed of guanine and cytosine, the second pairs is composed of the thymine and the adenine. The RNA is another nucleic acid which is usually composed of a simple bank molecule; it is shorter and has instead of the thymine, a nitrogenous base Uracil. The nucleic acid can be separate DNA by the centrifugation based on the density of the molecules which is higher in DNA after this RNA of separation is subjected to another method of separation which indicates the presence in the cell of three kinds of RNA. a- Compare basing on the text the DNA and the RNA. b- In your opinion, which of the molecules of DNA and RNA has more raised density? justify.

Exercise 3 The MTT assay is a widely used assay to study cell viability. It measures cellular metabolic activity, which serves an indicator of cell viability, proliferation and cytotoxicity. This non- radioactive colorimetric assay is based on the reduction of a yellow tetrazolium salt (3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide or MTT) to purple formazan crystals by metabolically active cells. Viable cells contain NAD(P)H-dependent oxidoreductase enzymes that reduce the MTT to formazan. The insoluble formazan crystals are dissolved and the resulting coloured solution is quantified by measuring absorbance at 500-600nm using a multi-well spectrophotometer. The darker the solution, the greater the number of viable, metabolically active cells! Exercise 3.1 MTT protocol Your colleagues in the School of Biology and Environmental Science discovered an unusual looking green algae on a recent fieldtrip to Costa Rica. They have provided you with some extracts from the plant…
