This research paper gives a brief overview of the most popular hypotheses on the origin of life. This includes Primordial Soup, Iron-Sulfur world, Deep Sea vent, RNA world, Community clay, and Panspermia. This document is stating information I researched about these hypotheses and I am giving some basic background information to the reader. If you don’t know much about these theories on how life began, then this is a good paper to read so you can get a general understanding of the hypotheses stated
would become autotrophs through mutation.However,evidence now suggests that the first organisms were autotrophs..The scientists involved in the hypothesis were A.I Oparin,J.B.S.Haldane, Stanley Miller,Harold Urey, Sidney Fox.Oparin and Haldane both independently developed the hypothesis in 1920.Miller and Urey tested the theory in
Life as defined by Knoll, a profesor of Biology at Harvard, is a system in which proteins and nucleic acid interact in ways that allow the structure to grow and reproduce (2004). Or in other words, one can describe life as having these six features; i) have carbon as a driving force, essential for it to grow and being able to make copies for itself and also must have the ability to convert the inorganic sources like carbon dioxide into organic molecules, in the case of hetrotrophics. ii) metabolism
behind the hypotheses which is what makes them even more interesting to test out. The hypotheses that I researched were the Primordial Soup Hypothesis, the Iron-Sulfur World Hypothesis, the Deep Sea Vent Hypothesis, the RNA World Hypothesis, the Community Clay Hypothesis and the Panspermia Hypothesis. The Primordial Soup Hypothesis was proposed by biochemist Alexander Oparin in 1924. He claimed that life started in a warm body of water due to a combination of chemicals
“Watch your thoughts, for they become words; watch your words, for they become actions; watch your actions, for they become habits; watch your habits, for they become your character; and watch your character for it becomes your destiny” (Donyes np). The simplest things such as our thoughts and words can impact who we become. Throughout life we become a product of our experiences. Kanakuk was one of those experiences that has changed my destiny. I could never imagine how this two-week long summer
Linking with the idea of hydrothermal vents being a 'reactor' for RNA hydrothermal vents rely on chemical energy from geothermal vents to sustain a organisms. Swarms of bacteria thrive in this environment which acts as an interface between the high temperature vents and cold oxygenated seawater. The bacteria thrive on
acid is a large part of the modern world as RNA (Ribonucleic acid) is one of the major macromolecules which are known for playing an essential role in all known forms of life. The most common function of RNA is that it is a copy of DNA and is used to create proteins and other organic compounds. To produce a certain protein, it activates the area of DNA that codes for a specific protein needed. Thus it replicates that section of DNA in the form of messenger RNA. Ribosomes are then used to translate
known scientifically as Homo sapiens sapiens, have evolved over time from other forms of life. Scientists are able to study some of this evolution through DNA and fossil research, but the exact process by which humans evolved and migrated across the world is still unknown. Genetic and archeological evidence can help scientists learn more about human history and create accurate timelines from human evolution and migration. Mitochondrial DNA plays an instrumental role in pinpointing how and when modern
1.1) Primitive conditions on Earth The conditions on early Earth, when dated back to 4 billion years, are very different now. Keeping in view the “Big Bang Theory” the conditions were very extreme in the terms of temperature. Consequently, the earth was extremely hot, causing the evaporation of liquid into the atmosphere. Gradually, as the earth cooled, the water vapors in the atmosphere condensed and fell as rain. They did not boil away but remained in pools that eventually converted into lakes

I find it interesting as to why
that these conditions were favorable for the synthesis of simple amino acids, which was the beginning of a series of experiments, modeled on this notion of prebiotic Earth, that created other more complex molecules needed to support life. Using the hypothesis set up by Urey and tested by Miller, this paper looks at whether these prebiotic conditions ever existed on the surface of Mars, thus making it possible to have or have had life on Mars. 1. Introduction Since the dawn of civilization, humanity

A continuing theme throughout much of the biological world is this relationship between form and function. When these small organic molecules are joined together, "giant" molecules are produced, This as we know it is a macromolecule. Macromolecules have a number of similarities and differences for example
Previous research and press coverage on the disease highlighted microcephaly in babies as the main detrimental effect of Zika virus. The speaker aimed to show the other less known facts and effects of Zika virus during the seminar. Zika virus is an RNA virus that belongs to genus Flavivirus which mostly cause exanthems. Although Zika virus has many vectors and
into the host cell may be accomplished by fusion of endocytosis, contingent on the particular strain. Host cell cytoplasm is the site of poxvirus replication, therefore host nuclear enzymes are unavailable to the virus; to overcome this, DNA-dependent RNA polymerase enters the host with the virus (Hughes). The wide host range of the Poxviridae family implies that they evolved from organisms that infected early life forms (Bray). The high accuracy of their DNA polymerase has resulted in the variola virus

theory of evolution was laid by Charles Darwin (Rose, n.d.). He developed hypotheses about natural selection which helped scientists develop the theory. Evolution is a theory and not a hypothesis because evolution has been proven by vast amounts of scientific data, research, and testing. The definition of a hypothesis is an educated explanation that needs to be researched and tested but has not yet been proven (Earman, 1984). There has been no scientific evidence to disprove the theory of evolution
COPING WITH THE AGING BODY Human bodies are not well built, powerful, or immortal, in fact, they are set up for failure. Biological, cognitive, and pathological forces knock on the door of survival every day intensifying its power of evil. At first, these changes are welcomed as one matures, grows stronger, and gets smarter, but it is an illusion of what is in store. These transformations slowly rob a person of who they were and what they were able to accomplish. People in all types of societies
The Origins of Life Before any speculation toward the origin of biotic forms, what was present at the formation of the earth that could result in inorganic, then organic, and later biotic creatures? Early atmospheric conditions have been theorized to be present due to planetesimal collisions releasing gases present in the Earth, after the initial atmosphere of Hydrogen and Helium escaped Earth’s gravity assisted by heat energy. The earlier atmosphere is believed to have consisted mainly of
Have you ever sat down and wondered where the heck did we come from? Well if you did this is the paper for you. In this paper the amazing Darshan Aidasani will be explaining everything about evolution, so sit down, relax, and get a bowl of popcorn because this is going to be interesting. What is evolution? Evolution is the process that all living things developed from primitive organisms over billions of years ago. Up to this day know one knows exactly how evolution occurs, but there are many theories
1. What were your first impressions of the main characters? James Watson: He can be seen as someone who is quick to judge, somewhat condescending, yet intelligent, suave, and dedicated to his work. Francis Crick: He does the same research with Watson and they are both teammates. He is also eager to know what is in DNA and the relationship of it with the double-helix, but at the same time is disorganised, and expected Watson to do a majority of work.
