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_forwardYou got an opportunity to join a professor lab who is working in-vivo model and specifically looking at the dysregulation of mitochondria in liver. He asked you to isolate mitochondria from a Rat liver and placed in an assay medium. Based on the knowledge you gain in this course so far, please answer the following questions: a) Which technique will you use to isolate mitochondria? b) What happens to the pH of the medium when the medium is kept anaerobic? c) What happens when O2-saturated saline is added to the mixture?arrow_forward
- Outline in general terms how small subunit rRNA has been used to define the three domains of lifearrow_forwardA bacterial species was isolated from a stool sample given by a healthy human volunteer. Researchers purified and cultured large amounts of the bacteria and sequenced its genome. They ran a comparison between the bacterial genome and the entire NCBI Genbank database (which includes the human genome sequence) and found a gene in the bacteria that showed 90% sequence homology to a human adhesion protein gene, but only 35% homology to other bacterial adhesion protein genes including those of other common gut commensal bacterial species. What conclusions could the researchers make from their results? The bacteria may have picked up and incorporated the human adhesion gene by horizontal gene transfer, after engulfing cell parts or DNA from human cells within the gut. All bacterial species living in the human gut may have originally had the adhesion protein gene that is homologous to the human version, but the gene became mutated in all the species except the one, which…arrow_forwardTo construct an “interactome” like the one shown in Figure 9-21, scientists identify all of the protein interactions in a particular tissue or cell type. Comparison of interactomes from human muscle versus human brain tissue reveals very different patterns.

In the light of what you have learned about the molecular structure and function of the gene, is this perspective still relevant? Cite specific biological phenomena to prove your point.
