The document contains 5 questions about early atmosphere and the origin of life on Earth. It asks about the universal genetic code shared by all living organisms, how this relates to hypotheses about the origin of life, how self-replicating molecules were essential to popular hypotheses, how genetic codes and proteins can determine how closely related species are, and which species humans appear most and least closely related to based on amino acid sequence data.

- 1. Questions for 1.05 Early Atmosphere Assignments. 1. What does it mean when scientists say that living organisms share a universal genetic code? The scientist means that all living organisms share a genetic code which all living organisms have a genetic code. Like Humans, animals , and other species have genetic codes and DNA 2. How does a universal genetic code relate to the hypotheses about the origin of life on Earth? The Universal genetic code relates to the hypotheses because it shares the formed life of earth. Like one true cell can pass genetic information to one microsphere to another microsphere. 3. 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? Like the RNA cells would pass on their genetic information and then it would help them explain why the species have the same or share the genetic codes. Reproduction.
- 2. 4. 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? It depends on the species DNA compared to another species to determine if the species are related or not. Like the human and the rhesus monkey they are closely related because all the genetic codes have the same DNA except one. 5. Based on the amino acid sequence data, what species do humans appear to be most closely related to and most distantly related to? Explain your answer I would say the Human and the Rhesus Monkey because they both have the same genetics but they only have different genetic code at least one genetic code that is different from the others. The donkey and the horses are distantly related.
