I dont understand #2,help?
2.Your model must contain at least 9 BASE PAIRS.
Answer:
When we speak of BASE PAIRS of DNA we are talking about the four so called purine and pyramidine compounds that code all DNA.
The four bases are Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). If you'll remember your chemistry (or genetics) you'll remember that A only pairs-up with T (and T only pairs up with A), and G only pairs-up with C (which means that C only pairs-up with G, as well). So, the four possible base pair combinations are A-T, T-A, C-G, and G-C. Using these four possible combinations every genetic trait is coded for every living thing on this planet; and that's pretty cool!
So, if you're constructing a "DNA Model," all that you have to do is to draw the DNA backbone with the Ts, As, Gs, and Cs on one side of the double helix, then you pair them with their corresponding base pair.
Happy drawing!
I'm pretty sure it's referring to each "base pair" as one rung in the DNA ladder.
A Base Pair is one of the pairs of bases that make up DNA: A-T or C-G in the DNA strand. A= adenine, G= Guanine, C= Cystine, T= Thymine.
Look at page 8 on the link below. Good Luck.
The guy above me is absolutely right!
