Video Tutor Session Quiz: DNA Structure

video

Part A
Correct
In this model, the deoxyribose sugar is the blue five-sided structure at the center.
Part B
Correct
A polynucleotide contains a sugar/phosphate backbone, where the sugar of one nucleotide binds to the phosphate of the next, and so on.
Part C
Correct
Remember the base pairing rules: A goes with T, and G goes with C. So the sequence GCAC matches with the sequence CGTG.
Part D
Correct
There are four kinds of DNA nucleotides, abbreviated A, T, C, and G.
Part E
Correct
The sugar and phosphate groups are the same for all DNA nucleotides. The base is the one part that changes.
