Biology Homework Help!?

Question

I am trying to answer the following question:

Draw two nucleotides (A and C). Show how they would be linked together in a strand of DNA, then draw the nucleotides that would be bound to them on the opposite strand. Be sure to include all of the components of a nucleotide and consider directionality!

Is there anywhere I can find this online, like a diagram or something? I know what the nucleotides look like individually but I am having trouble putting them all together. Thanks!

Answer 1

If you are doing this you probably learned about psb (phosphate sugar base). (That was the thing with all the octagons and lines) Well you draw to psb w/ the bases touching each other, because and c are both bases. I am sure if you look up psb  model you will find it
