RNA world theory, a possible theory for life origin I think the RNA world theory, combined with other process, including clay chemistry and deep sea vents activities, is an extremely possible theory for origin of life. With addition of icy chemistry, the RNA world theory may also help us to find life outside Earth. “The RNA world theory is widely accepted by origin-of-life theorist” (Ricardo and Szostak 2009) The RNA world theory was initially proposed 1967 for origin of life. It includes the following
The issue of the origin of life is one of the most controversial issue known to man. There are many proposed answers such at Divine Origin,Meteorites,Primordial Soup, and RNA world along with quite a few other. These different beliefs are supported by variety of people. In this paper I will share my beliefs on these different explanation of the origin of life. Divine Origin is the belief that the universe and the life on earth did not arise spontaneously, but was created by a divine creator. As
Viruses are one of the oldest and most diverse creations in the world. Viruses which are obligate intracellular parasites are studied by many who try to understand them and try to prove how they work, where they come from and how to classify them. The Baltimore system classifies them by how they replicate and the composition of their genome but classifying viruses is quite difficult. Viruses are not able to replicate on their own and require a host in which they hijack their cellular machinery and
In addition, this theory focuses on building the metabolism before information bearing compounds like RNA, while other theories focus on creating an RNA world first. However, the idea that hydrothermal vents were the hatchery of life can be compatible for both theories. Similar to how the micro-compartments in the vents could have concentration chemicals needed for metabolism to arise, the micro-compartments could have also concentrated products needed for organic synthesis of primitive genetic material
Charles Darwin published his book On the Origin of Species by Means of Natural Selection, which proposed the theory of evolution. This book, along with others that followed, began the long dispute between evolutionist and creationist. Were we created by a supernatural Supreme Being, or did our creation occur purely by chance? First, lets look at the two conflicting theories. Common usage of the term “evolution” is that living things in our world have come into existence through unguided

Theory of the Origin of Life being Underwater Hydrothermal Vents According to the Bible, God created the first man, Adam, from the soil and the first woman, Eve, from Adam’s rib. These events happened in the Garden of Eden almost six thousand years ago. That is one of the many beliefs of how carbon based life forms, otherwise referred to as living organisms, came to exist on Earth. Since the beginning of man’s reign on earth he has tried to explain his origins. He has used various religions
Quiz # 2 on lectures 3, 4, and including Chapter 2 1. Difference occurs in the sequence of long chain molecules and becomes information in biological organisms. ‘Life’ assembles itself into chains: (A) of RNA (B) all of the answers are correct (C) of DNA (D) of protein (E) none of these answers are correct 2. Which of the following foods is not a significant source of complex carbohydrates? (A) fresh fruit (B) rice (C) pasta (D) oatmeal (E) all of the above are significant
intervening of an outside party; this theory is part of the chaos theory. Case in point, rooms do not spontaneously clean themselves. To think that chemicals mixing in a primordial ooze for thousands of years can spontaneously decide to evolve into an entirely different substance without any outside action introduced is a ludicrous opinion and contradicts the laws of thermodynamics. Can there be creation without a creator? Many believe without a creator life is not possible. While Evolution can be said to
this topic I will start from the begging of the disease and discuss where it's at now. The HIV and AIDS disease has been around for awhile although no one has been able to pin point it's origin. There are many theories floating around the medical world but the most
