Science Homework Help. TCCD DNA Enzymes Restriction Enzyme Electrophoresis Chamber & Lambda Discussion

 

I’m working on a microbiology multi-part question and need a sample draft to help me understand better.

1. What is a restriction enzyme? Where do they come from?

2. The electrophoresis chamber must be filled with an electrophoresis buffer solution. Why can’t we just use water?

3. What is CRISPR-Cas9? How has it been adapted for use in genetics?

4. What is a restriction site? These sites are described as inverted palindromic repeats. What does that mean?

5. Is DNA positively charged, negatively charged, or neutral? Why?

6. Electrophoresis separates molecules based on three properties. What are they? 7. What is a DNA ladder? What does it indicate?

8. What are two reasons for adding loading dye to a DNA sample before conducting electrophoresis?

9. What is lambda? What is a plasmid? What are the possible shapes of a plasmid?

10. Indicate the number of bands that you would expect to see if lambda and plasmid DNA were cut by hypothetical restriction enzymes and subjected to electrophoresis.

Type of DNA Number of restriction sites cut Number of bands expected on electrophoresis gel

Plasmid (pGPS2.1) 0

Plasmid (pGPS2.1) 1

Plasmid (pGPS2.1) 5

Lambda 0

Lambda 1

Lambda 5

Science Homework Help. Macomb Community College Recipe Comparison Report

 

Type out (in full sentences) :

*Introduction (what is the purpose of this assignment?, what did you do?, what are the recipes?, etc

*A summary of the health benefits provided by changes (fat, cholesterol, etc) in the edited recipe. (ie if it has lower fat or cholesterol how is that a good thing?) Make sure to include the analysis of a minimum of 5 vitamins and minerals (for example, the healthier recipe had twice as much calcium than the first version. The benefits of getting more calcium in the diet are…”) You should analyze the entire recipe results rather than the individual ingredient changes.

*Discuss the possible drawbacks to the recipe (health, taste, calories, cost, etc). Conclude the paper.

Science Homework Help. RC Principles of Professional Identity & Professionalism for Nurse Report

 

Competency

Demonstrate principles of professional identity and professionalism for the nurse within the context of regulatory and practice standards.

Scenario

You are assigned to discuss your professional identity with your peers on the unit during a meeting and have decided to present the attributes using an infographic. The goal is to encourage all nurses to examine attributes and identify their professional identity to improve professionalism in the healthcare setting. As a nurse leader, you want your infographic to include the attributes that have guided your growth within the profession. As a leader of the unit, you work to grow the nurses on the unit and want to encourage them to identify their professional identity as the leaders to focus on succession planning. Your goal is to develop your infographic and share with other nurses to encourage them to examine the attributes to grow within the profession.

Instructions

Create an infographic that includes the attributes you believe support your professional identity. Include the following:

  • Identify 10 attributes that form your professional identity based on professional standards.
  • Reflect on why each of the attributes were selected for your professional identity.
  • Determine the attributes that are important for nurse leaders.
  • Identify how diversity and teamwork plays a role in developing your professional identity.
  • Provide stated ideas with professional language and attribution for credible sources with correct APA citation, spelling, and grammar.

Science Homework Help. AIU Environmental Policies and Climate Change Discussion

 

Can you help me understand this Environmental Science question?

Earth has warmed and cooled time and again as the planet received more or less sunlight, as the atmosphere or surface changed, or as the Sun’s energy varied. But in the past century, another force has started to influence Earth’s climate: humanity. (Riebeek, 2010)

Review the National Climate Assessment and The Effects of Climate Change resources.

  • Describe an example of the effect of climate change where you live (for example, rising sea levels, erosion, species decline, severe weather events, and so forth).
  • Discuss 1 approach to reducing greenhouse gas emissions, which are believed to have a large impact on climate change.
