1.Why is the epigenome considered our second genome?

2.How does epigenetics differ from traditional genetics? from epigenomics?

3.Explain how epigenetic events play a role in aging

4.Explain how epigenetic events control the formation of euchromatin and heterochromatin

5.Explain how epigenomics studies are conducted.

Please answer all questions in detail. Thank you

Briefly explain the process of atherosclerosis starting from endothelial injury to plaque formation.

please make it not that complex for non biology major student thx! :)

Assuming the electron transport chain received electrons from NADH and FADH₂ in a 3:1 ratio as the wild type for a particular organism, what would the consequences be of a change to a 1:1 ratio? Select all that apply.

a- Why would it be a problem to use only on resource when conducting research for a scientific experiment?

b- A food scientist bakes one cookie dough sample at 350F for 13 minutes and a second sample at 375F for 11 minutes. What is the problem with the scientist's procedure?

c- What would happen if a researcher failed to realize a thermometer he was using has both Celsius and Fahrenheit scales?

d- Explain how the measurements for length and volume are related

What are two regions that would be good targets for a test that would detect BOTH SARS-CoV and SARSCoV-2 ?

1. How do the three objective lenses on the microscope you used differ and what are the advantages and disadvantages of each?

2. How variable were the lengths of Paramecium caudatum cells relative to the lengths and widths of the cells you observed in Elodea leaves?

3. What size range did the single eukaryotic cells you examined span?

4. What subcellular features did you recognize and identify in all of the organisms you examined

5. Did you examine any prokaryotes in the pond or aquarium water you used?

6. How would prokaryotes and eukaryotes differ when viewed with a microscope?

7.What organisms were you able to identify in the pond or aquarium water you examined and how did they differ?

Compare and contrast between the two ATP generating energy systems: phosphagen system and the anaerobic glycolytic system. Base your answer on five different properties of each system and/or the type of activities they support.

Please write the answer for not a biology major (not too complex plz)

Give an overview of how Serratia Marcescens, Mycobacterium smegatis of bacteria might affect us as humans.

You engineer a strain of S. cerevisiae cells that express mutant histone octomer complexes that exhibit a negatively-charged DNA-binding surface. Which of the following would you expect to happen in a sample of these cells?

The chromosomes of the mutant strain would condense only during mitosis.

Nucleosome core particles would not form.

Epigenetic inheritance would be observed.

All chromatin in the mutant strain would be condensed.

The DNA would package too tightly for any gene expression to occur.

What DNA products would be generated if one of the proteins including DNA polymerase, DNA ligase, sliding clamp for DNA polymerase, nuclease that removes DNA primers, DNA helicase, and primase, were missing?

1. In the first set of experiments, you dissolve 1g yeast in either water, or 10% solutions of different sugars. At room temperature, you set up the eudiometers in parallel, with lots of air in each flask before you begin. These are the results. Plot them using the scatter plot function, set the Y intercept=0, and display the equations of the trendlines on the chart, with the title and axes carefully labeled. You can select/copy/paste the data shown in each table by clicking the little icon in the upper left hand corner or you may use the Excel spreadsheet provided on Canvas. Insert your graph below the data table and answer the following questions. For all of the eudiometer experiments the CO₂ is measured in cubic centimeters or milliliters of displacement (of the colored water).

a) Which of the sugars are being used for cellular respiration by yeast at room temperature?

b) What is the rate of CO₂ production for glucose in this experiment?

c) Explain why yeast might not be able to use the other sugars for cellular respiration.

d) Consider the molecular structures of glucose and maltose. How might these results differ if you used 1M solutions instead of 10% solutions?

5. Can risk assessment be used for both familial and non familial cases of cancer?

6. What are the tests used for early detection of non familial colon cancer?

7. Is cancer age dependent? Give reasons
