If you are fascinated with genetics and the various organisms and techniques used in biological development, this course is for you! It presents a fundamental understanding of how organisms evolve and the methods used to study genetic events such as mutation, DNA structure and function. You will learn what an organism is and how you can manipulate genomes indirectly by guiding breeding and deciding offspring with particular characteristics. Humans have approximately thirty-five thousand (35,000) genes. The majority of genes come in twos and are made of strands of a genetic substance called deoxyribonucleic acid (DNA). This course will introduce you to genetic engineering, which is altering the genetic structure of an organism. You will see why scientists and medical scholars found it necessary to modify diverse organisms’ DNA and how this breakthrough is beneficial to modern society. Is cloning possible? This course will assist you in answering this burning question.
This course will introduce you to different types of basic cell communication with particular reference to cell-cell communication. You will learn what kind of organism mainly use cell-cell communication and the importance of this cell-cell contact. You will be exposed to genetically modified plants and rodents and be informed as to whether they'll be fully functional as equals. You will know their pros and cons, if any, and ascertain the main reasons humans are interested in these experiments. This course will cover the history of modification and mutations. You will explore how these areas of study can significantly impact our lives. Can you imagine a world with no diseases and an extended lifespan for hundreds or even thousands of years? It was almost impossible in the early years to imagine a world without measles or the Spanish flu, yet these are under control.
Finally, this course aims to inform you about the past, the present and the possibilities for the future. It seeks to answer age-old problems and inspire more questions as time progresses. Organisms on this planet face many challenges. As one of the more complex organisms with the ability to display high levels of reasoning and problem solving, humans have a duty to protect our species and a responsibility to preserve other organisms' lives. Life is ever-changing; the world is ever-changing, and so is the climate. We need to understand our bodies and make whatever adjustments necessary to adapt to survive. Do you want to be part of the change? Are you ready to help humans and animals alike? Then don’t wait any longer. Enrol in this course today and make a difference!Start Course Now
