B) the plasmids multiply and produce the protein outside of the bacterium. C) the bacterial chromosome is genetically engineered and the plasmid is used to help the bacterium replicate. D) the desired gene is inserted into the plasmid and the plasmid is returned to the bacterium by transformation. E) the bacterial genome and plasmid are inserted into the genome of the cell containing the desired gene (perhaps the cell of a plant or animal).

Biology is the scientific study of living things and their vital processes. There are more than 10 million species of living things on Earth. They range from microscopic bacteria to huge blue what and towering redwood trees. Living things vary from where and how they live. Types of Biology Biology is a broad subject and that is why it is subdivided into separate branches for convenience of study. The four main subdivided branches are: ï‚ ³ Botany-the study of plants Read MoreBiology Final Paper : Biology1909 Words   |  8 Pagesgrandfather had to endure. When learning about Biology in high school I really enjoyed the subject and found that I had a natural talent in the subject. I took standard and AP biology and excelled in both, I began finding myself to be very intrigued by the subject, and the study of the human body and learned about the difference between plant, animal and human cells, their structure and function. My favorite thing that we learned about in biology was discovering the way our bodies react to differentRead MoreBiology2708 Words   |  11 PagesLaboratory Exercise #8 DNA Fingerprinting: Identification of DNA Restriction Fragmentation Patterns I. Introduction All humans have in common the coding sequences of their DNA, but, unless you are an identical twin, the non-coding sequences of your DNA are like no other person’s on the planet. The bulk of human DNA does not code for specific genes and is highly repetitive. A British geneticist, Alec Jefferies, developed laboratory techniques in 1984 that became known as DNA fingerprintingRead MoreWildlife Conservation and Biology Essay1571 Words   |  7 Pagesanimals as their everyday life. I should be a wildlife biologist so I can study land mammals. Wildlife biology is a field of biology in which land animals are studied. It deals with all animals with backbones and studies individual species of wildlife, their habitats, and surrounding ecosystems (Fitzgerald). It also studies how animals may interact with their ecosystem. Without wildlife biology we would not have extensive knowledge of other animal species, and how they could be linked to humans.Read MoreA Research Study On Synthetic Biology1324 Words   |  6 Pages2.1 Fundamental research Synthetic biology has a lot to offer in fundamental research. Starting from the most well characterised laboratory organism, E.coli, we are still in half way from full knowledge of understanding the function of all its genes as the functions of 20% of them are still to be identified (Keseler et al., 2011). Moreover there are many more other microorganisms with great importance which are even less-well understood. Synthetic biology provides the ability to make specificRead MoreBiology Field Study Essay1037 Words   |  5 PagesA general description of the area with reasons why the field study is being conducted. Geological overview Bicentennial Park which is located on the shoreline of Home bush Bay is a natural heritage site which features a vital wetland ecosystem and a large area of parkland colonized by a vast range flora and fauna. Within the park there are four communities of vegetation which are: Coastal Saltmarsh – a type of marsh that is intertidal between land and salty water, consistingRead MoreForensic Pathology, Toxicology, And Biology1077 Words   |  5 Pages Forensic science consists of a variety of fields such as in this case Forensic Pathology, Toxicology, and Biology were used to help solve the murder. Forensic Pathology was used to determine the cause of death by conducting an autopsy on the Johnson body. Coming to a conclusion, that Denise Johnson’s cause of death was due to asphyxiation (also known as strangulation)2,9. The pathology unit also determined that her death was a forced and violent death. Given the facts of how the victim died itRead MoreMarine Biology And Its Impact On Society1364 Words   |  6 PagesIntroduction Marine Biology is the scientific study of organisms in the ocean or other marine bodies of water. Marine Biologists are the examiners of this science. Marine Biologists play an important role in today’s society because 71% of the Earth is made up of water and only 5% of water on Earth has been discovered (â€Å"Ocean†). Without having these scientists in our communities today, the largest part of Earth would remain a mystery. The process of becoming a Marine Biologist is no easy task. ItRead MoreBook Summary of the Use and Abuse of Biology2361 Words   |  10 Pagesteaches. Marshall Sahlins, The Use and Abuse of Biology, is an excellent text, which attacks both the logical errors of sociobiology and its ideological distortions. His work focuses on demonstrating the power that culture has to shape peoples perceptions and actions and that culture has a unique power to motivate people, which is not derived from biology or for that matter any other of the natural sciences . In the text, The Use And Abuse of Biology, Sahlins reveals his true worries that cultureRead MoreThe Biology Of A Research Scientist983 Words   |  4 Pagestrial designing along with the improvement in my organization skills.
