17.1 Genes specify proteins via transcription and translation * George Beadle and Edward Tatum worked together with mutated (Neurospora crass) bread mold to figure out that they were missing a specific enzyme (gene) that catalyzed and synthesized a pathway required. They concluded that they were missing that enzyme because it was lacking the amino acid that coded for the enzyme‚ thus was mutated and incapable of growing. Led to the one enzyme-one gene hypothesis. The Products of Gene Expression:

suggest about women status in this play? What other evidence can you find to support your view? Measure for Measure is a play written by William Shakespeare in the seventeenth century which crucially presents the role of women. Women were viewed as pure and were not expected to be promiscuous‚ but dependent on men with few options or choices. Shakespeare’s interpretation of women in Measure for Measure very much reflects society’s opinion of women at the time‚ where men had more freedom and should

Compare and contrast the ways in which power and corruption is presented in Measure for Measure by William Shakespeare and other texts. In the play Measure for Measure‚ considered to be a dark comedy‚ Shakespeare shows the power and corruption of the higher characters within the society of Vienna‚ almost representative of the period it was written in‚ 1904‚ during the reign of King James I. The corruption of power can be shown through various manipulative techniques such as the female form‚ through

DNA is one of the nucleic acids information-containing molecules in the cell (ribonucleic acid‚ or RNA‚ is the other nuclei c acid). DNA if found in the nucleus of every human cell. The information is DNA: guides the cells (along with RNA) in making new proteins that determine all of our biological traits. DNA gets passed (copies) from one generation to the next.

Theme: Male/Female relationships and the role of women * Look at the way Shakespeare explores relationships between men and women in Measure for Measure. Consider how the male characters treat the female characters and in particular‚ how Isabella reacts to Angelo’s proposition When Shakespeare wrote Measure for Measure in approximately 1604‚ society was very sexist towards females and men were seen as the stronger sex‚ however Shakespeare included lots of strong female characters in his plays

This lab must be typed. Title DNA Fingerprinting Purpose Why are we doing this lab Background 1. What are restriction enzymes 2. When added to a DNA sample‚ what do restriction enzymes do 3. What do you call the specific sequence of bases the enzyme is searching for 4. What is a restriction digestion 5. What is the purpose of the water bath 6. The electrophoresis apparatus creates an electrical field with positive and negative poles at the ends of the gel. DNA molecules are negatively charged.

Give an account of protein structure and function Protein structure 1 Proteins consist of amino acids joined together (in chains) 2 A protein is unique because of the sequence of amino acids 3 The amino acids are joined by strong peptide bonds 4 to produce the primary structure 5 Further (weak) hydrogen bonding between acids 6 produce the secondary and tertiary structures A maximum of 4 marks can be gained from this section.

The evolutionary approach suggests that our behaviour is determined through natural selection; therefore it is coded into our genes through how we have adapted. It is a biological approach and states nature over nurture. A criticism of this approach is that it is determinist as it suggests that the way we behave is dictated through natural selection‚ for example in gender roles men being strong hunters and wanting a younger female partner. It ignores other suggestions‚ such as how we are brought

Cuttlefish Evolutionary History The cuttlefish are an amazingly developed animal species with many specialised traits that make them perfectly suited to most‚ if not all‚ types of underwater environments. This is the animal this presentation will be looking into. Evolution is commonly described as a theory‚ However that is a common misconception‚ all different types of evolution‚ e.g. Darwinism and Lamarckism‚ are actually considered both fact and theory. As palaeontologist Stephen Jay Gould says

Evolutionary Psychology This paper addresses a fundamental limitation in most attempts to apply the findings of evolutionary psychology to the human condition. Most attempts focus on how our biological past constrains and limits our behavioural options (including our cognitive abilities). They generally fail to look at whether these constraints can be overcome in our future evolution. To date‚ evolutionary psychology has not satisfactorily addressed a key question: are we beings forever constrained
