Archaea

Recombinant DNA is genetically engineered DNA that is formed by splicing fragments of DNA. Organismal cloning is the artificial creation of a new organism that is genetically identical to its counterpart. DNA cloning is a recombinant DNA technique where cDNAs and fragments of genomic DNA are inserted into a cloning vector and maintained during growth of the host cells. Vector is an agent that transfers genetic material into a cell or organism. Restriction enzymes are bacterial enzymes that find…

(a trait that put them at a disadvantage during the Permian Extinction, as they needed to eat more to maintain their body heat) synapsids, more specifically therapsids, in the Middle and Late Permian. Aquatic animals included early fish, bacteria, archaea, and invertebrates, such as trilobites, foraminifera, and ammonites (primitive nautiluses). Insects consisted mostly of primitive cockroaches, beetles, and early dragonflies, while vegetation included ferns and conifer trees, which replaced the…

Who or what is responsible for the occurrence of life on earth, and possibly many other planets, is a question that has plagued humanity for thousands of years. Once life was present on the planet, scientists largely agree that natural selection, the theory presented by Charles Darwin, took place allowing the hundreds of various species to emerge from one common ancestor known as the last universal common ancestor (LUCA) (Christian, Brown & Benjamin 2013, p. 57). Theories of how life actually…

Oral Microbiome 10: Reflection 3 One a daily basis the human mouth can come in contact with many different materials and organisms. “The human mouth is home to billions of individual microorganisms, including viruses, protozoa, fungi, archaea, and bacteria” (University of Minnesota Department of Biology Teaching and Learning, 2016, p. 21). In specific, during this lab we are looking at Streptococcus mutans (S. mutans) and Lactobacilli. In studies, it has been shown that yogurt has helped…

Materials and method Microorganisms are classified in to the three domains of life. The organism that is predominately found in our environment is bacteria closely followed by archaea and eukaryote. Although, microorganism might seem similar, they are different interims of their structures, biochemical composition, and the habitat they adopt. Conducting an extensive test on microorganism has many benefits. We can protect our self’s from different types of infectious disease. In the unknown…

Measurable Outcomes 1. Describe and demonstrate knowledge of modern evolutionary synthesis, natural selection, population genetics, micro and macroevolution, and speciation. I learned about the speciation of animals in Module 3 and in Module 4 I learned about modern evolutionary synthesis, natural selection, population genetics, and mirco and macroevolution. I was able to learn all this information due to the chapter 46 and chapter 47 notes, the online textbook, and the PowerPoint notes. This…

The variability of the human gut microbiome and its effect on health Abstract The human gut microbiome consists of a wide range of microbes such as bacteria, fungi and archaea which can be found in the gastrointestinal tract. This gut microbiome can have both beneficial and harmful effects on the host. On one hand, it is involved in processes such as modulation of the immune system and metabolism which are beneficial for the human host. On the other hand, an imbalance in the gut microbiome…
