What is a 4.0? In the university grading system PERCENTAGE of mastery = PERCENTAGE grade Quantity

What is a 4.0? In the university grading system Quality Quality of work = Level of grade

What is a 4.0? In the university grading system If a student does what was asked of them on an assignment and does a pretty good job what’s the grade supposed to be? a.4.0 b.3.5 c.3.0 d.2.5 e.other

What is a 4.0? In the university grading system The “4.0” is Outstanding is the student blew you away with how much and how well they did the work. They taught you something you didn’t know. A “3.5” is Most Excellent every detail of their work was done extremely well and they found additional papers and evidence beyond what they were told/expected to do, to complete their work.

Integrating Questions 1. Which carbon in dATP is missing the oxygen found in ATP? Which deoxyribose carbon is attached to the string of three phosphates? A. Carbons # 3’ and 5’ respectively B. Carbons # 2’ and 3’ respectively C. Carbons # 2’ and 5’ respectively D. Carbons #2 and 3 respectively E. None of the above

Integrating Questions 2. Speculate why a triple- stranded DNA molecule with the negatively charged phosphates in the center would be unstable and thus not a good model. A. phosphates would attract B. phosphates would repel C. phosphates are too big to fit D. phosphates would form covalent bonds E. None of the above

Integrating Questions A. One strand’s words should spell backwards B. One strand’s phosphates should move inside C. One strand should be upside-down D. More than one hydrogen bond should be there E. None of the above 3. Look at the Figure and find the misleading aspect of the diagram, given the two strands are supposed to be anti-parallel. What should be done to correct this historic figure?

Integrating Questions A. A=T have two hydrogen bonds B. G=C have three hydrogen bonds C. G + A are bigger and C + T are smaller D. two bases cannot pair with just one E. None of the above 4. If the DNA had a uniform diameter of 20 Å, why did the bases have to pair one A for each T, and one G for each C base?
