Biology Digestive and Skeletomuscular Systems Questions
I’m working on a biology question and need an explanation and answer to help me learn.
1.(1) You just ate a sandwich during a wonderful seminar and your body is working hard to extract the nutrients. Describe the journey your food will take through your key digestive systems, starting from ingestion to excretion.
- (2) Describe oneaspect of the digestive system that can decline with age and how that will affect the health of an elderly person.
2.Based on the age-dependent changes of the skeletomuscular system discussed in class:
- (1) Describe one major physiological change that can occur to the skeletal system.
- (2) Describe one major physiological change that can occur to the muscular system.
For both (1) and (2), elaborate why the change happens and how it will affect the way we age.
Bacteria Differ from Humans and DNA Ligase Essays
Essay #1 Biology Digestive and Skeletomuscular Systems Questions
A researcher is interested in studying the human CFTR genes and decides to insert a functional human CFTR gene in a bacterial line using molecular biology methods. Before she decides to proceed with her methodology, she comes to you and asks for your opinion. In your answer consider how bacteria (Prokaryotes) differ from humans (Eukaryotes). What are
the differences in RNA processing between Eukaryotes and Prokaryotes? Are there molecules or structures involved in translation or translation that may differ between these two organisms? Lastly, compare and contrast the regulation of genes between these two organisms.
Essay #2
Enzymes play an important function in cellular biology. We recently discussed the following four enzymes: Biology Digestive and Skeletomuscular Systems Questions
1) DNA ligase
2) DNA Polymerase
3) RNA Polymerase
4) HelicaseDescribe in detail the function of each of these enzymes. What process are they are part of? What nucleic acids are they in contact with? Where would they be found in a Eukaryotic cell? Additionally, describe the consequences for a nonsense mutation in the DNA sequence for each enzyme.
