- All life shares DNA as the hereditary material. From an evolutionary perspective, why do you think this is the case?arrow_forwardResearchers have reported advances in their attempts to synthesize life from scratch in a test-tube—bringing non-living matter to life. In the lab, they have been able to produce ‘protocells’ from fatty molecules that can spontaneously trap pieces of nucleic acids that possess the code for replication and metabolism. With continued progress, protocells may be synthesized that form self-replicating, evolving system that satisfy the conditions of life. Consider the scientific understanding that may be generated from this project. What scientific questions might the knowledge generated from this project help answer? Reflect on the broader significance of this work. What objections might be raised about this line of research?arrow_forwardIn a discussion about the origin of life, one student argued that RNA molecules must have come before DNA molecules. What is the most likely rationale for this argument? RNA can both store genetic information and catalyze chemical reactions, which are necessary for self-replication. RNA is more stable than DNA, making it more suitable for early life forms. RNA can replicate faster than DNA, enabling rapid evolution. RNA can translate genetic information into proteins, whereas DNA cannot.arrow_forward
- (a) Why can there be multiple codons for an amino acid? Why would this have evolved? (b) What is the advantage of Illumina Next Generation Sequencing?arrow_forwardSuppose that life exists elsewhere in the universe. All life must contain some type of genetic information, but alien genomes might not consist of nucleic acids and have the same features as those found in the genomes of life on Earth. What might be the common features of all genomes, no matter where they exist?arrow_forwardWatson and Crick’s discovery of DNA is clearly one of the most importantbiological discoveries in the last century. What advances in medicine and science can you think of that are built on knowing the structure of DNA?arrow_forward
- Neema wants to determine whether or not the nucleus of a cell differs in the chemical compounds they contain or not from species to species. She is planning on working with the nucleus of a human and the nucleus of a mouse. She has removed all of the DNA from each nucleus, then has selected and isolated one DNA fragment from each species. What results can Neema expect if she takes the human DNA fragment and inserts it into the mouse nucleus and then inserts the mouse DNA fragment into the human nucleus? Use your knowledge of DNA replication to answer.arrow_forwardIf only part of the genome contains genes, why sequence the whole thing?arrow_forwardHighly conserved genes such as those for ribosomal RNA are present as clearly recognizable relatives in all organisms on Earth; thus, they have evolved very slowly over time. Were such genes “born” perfect?arrow_forward
- Which of the following is the primary function of RNA molecule? A) transmit genetic information to offspring B) make a copy of itself, thus ensuring genetic continuity C) function in the synthesis of proteins D) act as a pattern or blueprint to form DNAarrow_forwardIf life were found on another planet, do you think that itwould have the same genetic code? Justify your answer.arrow_forwardClearly, all humans have variations in their DNA sequences. How is it possible to sequence the human genome if every individual is unique? How was the diversity of the human genome addressed?arrow_forward
