Concept explainers
To determine:
The production and use of biofuels in the United States and also the role of government, private industry, and scientists in promoting the production and use of biofuels.
Introduction:
Biofuels are the substitutes for fossil fuels and are derived from renewable animal and plant biomass. Biodiesel and ethanol are the two types of biofuels.
To determine:
Whether citizens have an ethical responsibility to use biofuels as a substitute for fossil fuels and provide a reason for the same.
Introduction:
Ethanol, biodiesel, and biogas are examples of biofuels. Ethanol is often made from corn or sugarcane. Biogas (methane) derives from animal manure and other digested organic material.

- Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forwardMolecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was successfully transcribed and translated, it produced a different protein than it produced in the eukaryotic cell. What is the most likely explanation?arrow_forward
