Given the rich diversity of life, we might expect organisms to have an enormous variety of molecules. However the significant large molecules of all living things can be classified into four categories: carbohydrates, lipids, proteins, and nucleic acids. Only three of these categories- carbohydrates, proteins, and nucleic acids- are huge on a molecular scale and are [...]
Hey all! This blog post is a part of STEMTalksNC’s ever expanding General Biology Series. In this post, it would be helpful to know high school chemistry. Although water is the universal medium for life on Earth, living organisms are made up of chemicals that are based mostly on the element carbon. Of all chemical [...]
Living Organisms are distinguished by their ability to reproduce their own kind. Heredity is the transmission of traits from one generation to the next. Along with these these inherited traits, there is also variation- the offspring differ somewhat in appearance from parents and siblings. We will first establish that offspring acquire genes from parents by inheriting chromosomes.
Today, it is widely known that DNA is the genetic material. However, the identification of the molecules of inheritance came as a major challenge for biologists in the 20th Century.
Hey all! This blog post is a part of STEM Talks' ever expanding General Biology Series. For this post, it is recommended you understand the basics of cell division and cell cycle phases. The cell cycle seems to be governed by cytoplasmic and extracellular signals. A cell cycle control system controls the cell cycle. It [...]
