There is a cell called “originator”  that over generations and being passed down has been able to modify organisms even to this day. How does a universal genetic code relate to the hypotheses about the origin of life on Earth?People think that single organisms over time have been modified and able to create billions of other organisms. The ‘Universal Genetic Code’ looks at the similarities of different organisms and compare them. Then they are able to say what types of organisms came from a single organism in the beginning of Earth.How are self-replicating molecules, such as RNA molecules in the “RNA World” hypothesis, essential to the most popular hypotheses about the origin of life on Earth?The most popular hypotheses are the Self-replicating molecules, for example: RNA molecules in the “RNA world”. They are known to be involved with the origins of the Earth. People believe that RNA molecules can self-catalyze, which brings up the possibility that early RNA molecules could self replicate without other organisms. It would make sense, because all organisms contain the same genetic code. How might similarities and differences in genetic codes, or the proteins built as a result of these codes, be used to determine how closely related different species are?There are similarities and/or differences in genetic codes, or proteins built by the codes are in the organism’s DNA sequence. The closer two genetic codes are in similaritie, the higher the chance that they had a common organism in Early Earth. Humans and chimpanzees have very similar genetic codes, which is why we say that we are very close together. Based on the amino acid sequence data for the Cytochrome-C protein, chimpanzees and humans share an identical coding sequence. What other species identified on the chart has a coding sequence that is most closely related to the humans and chimpanzees and most distantly related? Explain your answer.Looking at the amino acid sequence in our Cytochrome-C protein, Humans and chimpanzees have identical coding sequences.Another species on the chart would be the Rhesus monkey since it had 0 differences with chimpanzees/humans. Our most distantly related organism isCandida Yeast and Neurospora.They both had 19 differences.
