Explain the structure and inheritance of genes (15 marks) A cell’s nucleus contains chromosomes‚ which are long‚ coiled packaged and organized chromatin (molecules of DNA). Chromatin is a complex of molecules found in cells‚ consisting of DNA‚ protein and RNA. Proteins are polypeptides (a large sequence of amino acids). The chief protein component of chromatin are histones‚ which package and order the DNA into structural units called nucleosomes in order to fit in the cell‚ as well as reinforce the

Discuss the ethical issues involved using deception in researching human behaviour When conducting any kind of research‚ one must be aware of the ethical issues involved. Almost all research in psychology studies human behaviour. Before the experiment is conducted‚ all subjects are given a brief overview of the experiment but will not be told about the entire experiment and its true purpose. This deception leaves the subjects vulnerable which may arise to ethical issues. Back in 1954‚ W. Edgar Vinacke

How Primary Structure Determines Protein Function Proteins are everywhere. As enzymes‚ they catalyse chemical reactions. There are many different types of proteins: carrier and channel proteins which transport substances‚ receptor proteins which are recognition site for antibodies and hormones‚ structural proteins which support cells and tissues‚ and hormones which transmit information. Proteins are big molecules with large molecular masses that are made up of many amino acids; they’re‚ essentially
