Introductions to biotechnology (Code: BT150IU‚ BT150UN‚ Bt150WE) COURSE OVERVIEW This course presents the summary of aspects of biotechnology including the history‚ the general view of molecules and cells‚ immunology‚ microbiology‚ plants and animal‚ genomics and their own applications. Each major is structured in one lecture. The lectures are organized in lessons with theory and applications. Students attend the class will be required to prepare an assignment on which they most concern in biotechnology

Unit 2 M3 Justifying the key features in a specialist and not specialist lab Lamina Flow Laminar air-flow systems have been used by biological industries to control contamination by dust and other microorganisms which can affect the reliability of precision parts. Laminar flow units consist of ultrahigh-efficiency filters which are surrounded by a cabinet or a hood. The air stream which travels at extremely high speeds‚ moves in parallel patterns so that the cleanliness of the air is independent

AQA Exam-style Questions Cell activity 1. a) - A : nucleus - B : mitochondria - C : ribosomes - D : plasmids b) The nucleus controls all activities within the cell. It also contains genetic materials used to create new cells. c) Plasmids and genetic materials in cytoplasm d) i 75 ii 28 iii 0.15 e) Protein can be used to build up cells as it is a structural component of every cells. It is also an enzyme as well. f) There are no mitochondria in bacterial cells because they are

Chapter 3 The Body I. The cell The cell is the basic unit of life in our bodies. It has many “little organs” in them called organelles. Organelles have very specific functions. One example of an organelle is the mitochondria. Cells require nutrients and get rid of waste and live and die- just like us. II. Tissues‚ organs‚ organ systems Cells group together and form _____________________________ Some examples are: Tissues group together and form

In Crash Course video number four you learn animal cells and how they operate more like a city. Hank calls this city Eukaryopolis- The city of animal cells. He also goes over what each part of the cell and how the animal cells are responsible for different things that happen in our body. The very start of video starts off comical by showing you the difference between what an animal is and is not. Then it goes on to explain that why a eukaryotic because they have a “true kernel‚ meaning good nucleus

Chapter 7 * Why do we want to make Eukaryotic cell proteins? * Because when eukaryotic proteins are expressed in prokaryotic cells problems like been unstable‚ no biological activity and prokaryotic contaminants ( pyrogens) can occur. * Also to make the protein as natural as possible * The same expression vectors as we need for pro * We don’t need shangdolron coz that only for pro Transformation: in Eukaryotic cells: in humans means that difference in growth characters

It is important that cells go through mitosis because it makes each new cell contain the same gentic information. If meiosis did not occur the reproduction would cease to exist. Mitosis is the process of chromosomes dividing. There are four steps that it goes through. Between cell division the cells are in interphase. During this there is cell growth and the genetic material such as DNA is contained in the chromosomes‚ duplicated so that when the cell divides each new cell has a full version of

4.I believe that our observations are repressentative of cell division taking place in the oinon root tip. Firstly‚ this is because our numbers of the number of cells in each phase of mitosis are similar to the rest of the groups‚ so we can assume our results are most likely correct. We can also assume our calculations are right because we know that Interphase is the most active phase in the process of cell divison‚ which would agree with our calculations since we assume that approxiamtly 93% of

Lab 4 – The Cell Answer Key Procedure 4.3 Draw a picture of a single Elodea cell and label all visible structures. See the diagram in your lab manual. Without staining‚ the only structures that should have been clearly visible should have been the cell walls and the green chloroplasts. Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________ What evidence do you have to support this claim? The presence of organelles (chloroplasts) and its large size.

Introduction A chromosome is a minuscule threadlike part of the nucleus and a structured DNA in the form of genes carrying hereditary information (Bridges‚ 1938). Endomitosis is the process of mitosis of chromosomes without undergoing nuclear or cellular division to increase cell volume. This results in a single nucleus having many copies of a single chromosome (Painter & Reindorp‚ 1940). In this experiment‚ Drosophila melanogaster is reared in specific conditions and its salivary gland extracted
