Bioinformatics: Investigating Metabolism NOS: Developments in scientific research follow improvements in computing: developments in bioinformatics, such as the interrogation of databases, have faci...
Enzyme Inhibitors Inhibitors?are chemical substances that can bind to an enzyme and?reduce its activity Inhibitors can be formed from?within the cell?or can be introduced from the?external environm...
Metabolic Pathways Metabolic pathways involve a?series of small steps, each step involves a?chemical change The?enzyme-catalysed?reactions that make up metabolic pathways usually consist of?chains?...
Identifying Polysomes Translation can occur?simultaneously?at?multiple positions?along mRNA Polysomes?(or polyribosomes) are groups of two or more ribosomes translating?the same mRNA?transcript Mul...
Primary Structure Levels of Protein Structure Proteins are relatively?large,?complex molecules?that contain?one or more chains?of amino acids known as?polypeptides The?three-dimensional arrangement...
Bioinformatics The 21st?Century has seen a tremendous?increase?in the amount of?biological data This has been due to rapid advances in?DNA sequencing?and other technologies Developments in scientif...
Translation in Prokaryotes Prokaryotic cells have a?less complex ultrastructure?than eukaryotic cells Eukaryote cells are divided up into membrane-bound compartments called organelles Transcription...
Structure of Ribosomes Ribosomes?are found in cells Either?freely?in the cytoplasm (of all cells) Or bound to the?endoplasmic reticulum?(ER) to form?rough ER?(only in eukaryotic cells) Ribosomes ar...
Initiation of Translation Initiation of translation involves assembly of the components that carry out the process. During translation, the specific sequence of messenger RNA (mRNA) is translated t...
