Because all known living organisms share a common system for storing and utilizing genetic information, it would suggest: that all life forms on Earth share a common ancestor that the study of one organism’s genes may reveal principles that apply to other organisms thatgenesfromoneorganismcouldpossiblyfunctioninanotherorganism that all of the above ideas (1-4) are likely
Science fiction movies have been known to sketch out a world of the near-future where terrible things have happened such as the evolution of antibiotic resistance in flesh-eating bacteria. What might we reasonably say about this topic? (Select all that apply) A - While one can have fun with entertaining stories about evolution (including ones that are very plausible), this is not a good reason to fund research on antibiotics because that is a solved medical problem. B - It has already happened with some early antibiotics (like penicillin)-the only reason we are momentarily okay is the continued development of additional antibiotics. C - In principle, it is possible but evolution takes millions of years, so don't expect it in the near-future. D - The bodies of humans have evolved since the discovery of antibiotics such that they are less and less effective already. E - We shouldn't find antibiotic resistance to be evidence for evolution because it is only a science-fiction story: it…
Which of the following is not a reason why RNA is expected as one of the first primary molecules in the earliest living life forms? RNA can self replicate with errors which will lead to selection RNA can perform work on other molecules RNA can store information RNA uses uracil which is more stable than the other nucleotides
If all living organisms have the same pattern, then humans would have the same genetic code as a worm because all species have the same repeated pattern, DNA could not provide the variety needed for the genetic code. Was the hypothesis supported? Be sure to explain your reasoning! (Sentence starters: “Yes, my hypothesis was supported. I know this because…” or “No, my hypothesis was not correct. It was proven to be false because…”)
The Miller-Urey experiment is significant because it produced evidence that It is possible to have an RNA World with the condition on earth 4 billion years ago. It is possible to produce Last Universal Common Ancestor in the laboratory. It is possible to create amino acids with the condition on earth 4 billion years ago. It is possible to recreate the condition on earth 4 billion years ago to generate ribozyme.
According to the seven characteristics of life (1- composed of one or more cells, 2- compelx and organized, 3- respond to environment, 4- grow, develop, and reproduce, 5- obtain and use energy, 6- mainatin homeostasis, 7- allow for evolutionary adaptation), are viruses alive?
Stanley Miller’s experiment demonstrated that ________ .a. Earth is more than 4 billion years oldb. under some conditions, amino acids can assemblespontaneously from inorganic materialsc. oxygen is necessary for all lifed. RNA was the first genome
Scientists Stanley Miller and Harold Urey set up an experiment modeling the environmental conditions thought to exist during the early stages of Earth's formation. The setup of Miller and Urey's experiment is shown below. Which conclusion about the origin of life could be drawn from the potential results of this experiment? Life assembled from chemical building blocks. Life began when water vapor became electrified. Life evolved from the DNA of simple unicellular organisms. Life began when salt water caused a mutation in an ancient virus.
An astrobiologist discovers a new form of life on another planet. Life here appears to have evolved using DNA as the information storage molecule and proteins to carry out cellular function, much like on Earth, however the individual building blocks on this planet are different. On this planet, there appear to be 3 different nucleotides in the DNA and 30 different amino acids in the proteins. Which of the following conclusions about this form of life would be most justified? These organisms can produce proteins no more than 30 amino acids in length. These organisms must produce 30 different forms of mRNA Amino acids must be coded by sets of 3 nucleotides in the DNA of the organisms on this planet. Amino acids must be coded by sets of at least 4 nucleotides in the DNA of the organisms on this planet. These organisms cannot produce more than 30 kinds of protein.
The "molecular clock" of the rate of change in a segment of DNA during evolution depends on which of the following? (select all that apply) • A process called purifying selection • Whether that DNA contains functionally important sequences • Whether the DNA can be easily sequenced • The structure of the RNA molecule produced from that DNA The rate that mutations occur in that species or type of DNA Message @ProBot ✨
The ability of genomes to respond to the outside environmentby changing the developmental trajectories of organisms opens up entire worlds of research. Is evolution selecting “teams” of organisms?
How does DNA analysis help scientists better understand evolution? It spells out the amino acids that make up an organism. It helps chart changes in amino acid sequences over time. It shows us what codons an organism has. It shows us an organism’s genome sequence.
