October 1962 was one of the most dangerous times for the world in recent history. The text being examined in the essay is that of an extract from the Kennedy Tape transcripts. These were a set of secret tape recordings that President J.F Kennedy had made during his time in the white house. The only people aware of these recordings at the time were J.F Kennedy himself‚ his private secretary‚ the two guards who manned the machine and perhaps his brother‚ Robert Kennedy. The conversation that was recorded

Bread mold can grow in a minimal medium without supplements (wild type) while certain mutated strains (mutants) can only grow in a minimal medium that is supplemented with specific intermediates found in the following metabolic pathway for arginine synthesis: minimal ------> ornithine -------> citrulline ------> arginine‚ where enzyme 1 converts the precursor to ornithine‚ enzyme 2 converts ornithine to citrulline‚ and enzyme 3 converts citrulline

A. Genetics Ribosomal 5S RNA can be presented as a sequence of 120 nucleotides. Each nucleotide can be represented by one of four characters: A (Adenine)‚ G (Guanine)‚ C (Cytosine)‚ or U (Uracil). The characters occur with different probabilities for each person. We wish to test if a new sequence is the same as ribosomal 5S RNA. For this purpose‚ we replicate the new sequence 100 times and find that there are 60 A’s in the20th position. Use a 0.05 level of significance. 1. If the probability

(Beadle and Tatum‚ 1941) • • • Cellular machinery is largely made up of proteins. Proteins are made up of chains or sequences of amino acids. The sequence of these amino acids are "encoded" in the cell’s DNA. DNA is transcribed into RNA‚ which is then translated into protein. When one gene is mutated‚ one protein is affected (usually

B) enzymes are made of DNA‚ and affected individuals lack DNA polymerase. C) many metabolic enzymes use DNA as a cofactor‚ and affected individuals have mutations that prevent their enzymes

Transfer RNA(tRNA) carries amino acid during protein synthesis‚ ribosomal RNA molecules come together to form ribosomes while mRNA bears the message for protein synthesis. In bacteria‚ mRNA often carries coding information of more than 1 gene therefore it is said to be polycistronic (DIAGRAM). MRNA is synthesized under the direction of DNA by RNA polymerase. This polymerase in its core enzyme form has 5 subunits. A 6th
