Please help me!
For letter A, pls ILLUSTRATE (create an illustration or drawing) the DILUTION SERIES of the problem just like the sample on the 2nd image.
Please read the instructions carefully as I have already posted this twice and the experts just copy-pasted the answers from my first post. I don't want to waste another post question for this one. Again, I NEED AN ILLUSTRATION and not just the computation/explanation through words so I can properly visualize the problem.
WILL UPVOTE if I get what I need.
Instructions
Using the Concord Consortium interactive, observe how mutations can affect protein
formation and function. From your observations of the interactive, summarize your
observations of how each change in DNA affects the protein that is made.
Screenshots will be required for your assignment. Interpret and analyse your results:
identify the type of mutation, and describe and explain the effect of each change on
protein size, shape and polarity.
Create two different mutation types and observe the different outcomes.
