Question

Week TCO 1) The basic principles of genetics contributed by Gregor Johann Mendel are TCO 11 The Augustinian monk, Gregor Johann Mendel,/crossedvellow-seeded and green-seeded pea plants and then allowed the offspring to self-pollinate to pro an Fa generation. The results were as follows: 6018 yellow and 2002 green (8020 total) The allele for green seeds has what relationship to the allele for yellow seeds? endel,crossedyellow-seeded and lowed the offspring to self-pollinate to produce (Tco I in 1953 James Watson and Francis Crick proposed The Clouble helik os a woclel for the Sructure oF DNA DAJA Question Set 2 (TCO 1) In 1928. Frederick Griffith discovered that Streptococcus pneumonia caused pneumonia in mice. In his experiments, mice were injected with different strains of treated and untreated bacteria. Which of the following is not likely to have occurred in the series of experiments by Griffith? m'ce injectee uthm funn TCO 1) In 1928, Frederick Griffith injectedliving S (smooth) Streptococcus pneumonia into mice, and the mice died. When he injected living R (rough) Streptococcus umonig into mice, the mice lived. When he injected heat-killed S bacteria into pne mice, the mice lived R bacteria and injected this mixture into mice? What was the result when he mixed heat-killed S bacteria with live In 1944/Oswald Avery Colin Macleod, and Maclyn McCarty used an in vitro (TCO 1) I agglutination assay f transformation of o demonstrate that purified DNA was sufficient to c cells, and that the transforming facfor could be destroyed by ause

Explanation / Answer

1 ans-the basic principles of genetics contribute by mendel are-

2 ans-yellow seeds-6018

green seeds-2002

yellow is dominant over the green seeds.where as green seeds is recessive.

3 ans-Duble helix, antiparallel, structure of DNA .

4 ans-the results are as follow-

Live S bacteria inject into mice -die

Live R bacteria inject into mice-Live (do not have the capsule )

Heat killed S bacteria inject into mice-live

Mixture of live R bacreria and heat killed S bacteriainject into mice-Die

ans-5-Mixture of live R bacreria and heat killed S bacteriainject into mice-Die

Griffith concluded that there was transformation which shows the role of DNA as a genetic material.
