Microbes - bacteria, archaea, fungi, algae, protozoa and viruses - have been around for at least 3,500 million years and were the only life forms on Earth for most of that time. Microbiology is the study of these small organisms. A microorganism or microbe is an organism that is microscopic. The development of the microscope, along with the observations of various scientists, led to the discovery of microorganisms. It is thanks to Van Leeuwenhoek who is largely credited with the discovery of…

250,000pg/µl = 250µg/ml 1mg/ml = 1000µg/ml ● 150,00µg/ml - HIGHEST CONCENTRATION OF DNA ● 1000µg/ml ● 250µg/ml ● 0.2µg/ml - LOWEST CONCENTRATION OF DNA 4. Sodium dodecyl sulphate is used as a detergent, which allows the cells to release DNA by disrupting the cell and nuclear membranes. It dissolves the proteins and lipids that hold the membranes together. 5. The isolated DNA can be used to diagnose genetic disorders, investigate forensic evidence…

Based on Mendel’s experimental observation and conclusion on pea plants, he proposed four postulates including one that each phenotypical characteristic are controlled by a pair of unit factors also known as alleles that separate independently in gametes. Although Mendel’s contribution to genetics isn’t wrong, there are some exceptions of inheritances that do not follow Mendel’s principles. Non-mendelian inheritance traits include maternal effects, epigenetics, and extranuclear genes. What makes…

into a human and some people do not agree with this. Process and Biological Concepts There are 2 main types of xenotransplantation that can occur: Solid organ and Cell and Tissue transplantation. Solid organ as the name suggests is when an animal organ e.g. kidney or heart is transplanted into the human body. Cell and Tissue is when cells and tissues are…

Information is Useful: This lab is an example of how cell transport works. The gummy bear is a cell in this case which is placed in a hypotonic solution that is the lime juice. Hyp0tonic solution is a greater concentration of the solute molecules inside the cell than outside. The gummy bear has an outer layer, cell membrane, and a jelly substance in the middle, cytoplasm, which relates to a cell. Seeing how the gummy bear reacts would be similar to how a cell reacts to another substance.…

Gregor Mendel was the first person to make connections between parents and children by using math symbols. He made the set of laws which are now known as the three laws of inheritance. This set of laws consists of the Law of Dominance, the Law of Segregation, and the Law of Independent Assortment. To begin, the first law of inheritance is the Law of Dominance. This law states that genes come in pairs and are inherited in different units called alleles. In a situation with one dominant allele and…

The human body is arguably the most researched organism on Earth. The intricate relationship between molecular, anatomical and physiological characteristics of it astounds me, yet what interests me most is not how powerful the human body is as a whole, but how ultimately our physiology can fail us. Studying biology at an undergraduate level will allow me to grasp a deeper understanding as to why this happens, as well as develop my existing knowledge of the mechanisms involved in keeping humans…

In 1932 a new novel hit the shelves, a topic one that no one had thought to type out and bring to life before. Aldous Huxley published his book, A Brave New World. He writes about our society many years in the future and our advanced technology. Natural reproduction was replaced and humans were created in laboratories. The government constructing a damming caste system. Children are created with specific genetic factors in mind, designing them to do certain jobs, and only those jobs. The result…

scientists see the cells better and distinguish the different organelles inside the cell. 2. Prokaryotic cells do not have a nucleus and most internal structures that eukaryotic cells. 3. This method builds on the work of early scientists by changing the soup broth with bacteria in it to a preserved petri dish. 4. Both cells and atoms are basic building blocks. 5. This poison would not kill bacteria because bacteria do not have a nucleus. 3.2 1. The cytoskeleton provides support for the cell…

Imagine this; a world where no one has lifelong infections or medical conditions. This might be made possible soon; however, some are afraid that parents will take it too far. With enough money, they could transform their babies to be intelligent and good looking. In my opinion, genetic engineering should be allowed, but restrictions should be in place to stop parents from making super babies. Genetic engineering is the purposeful changing of an organism's DNA. It can be used in ways that…
