question 2

Multiple Choice

Which conclusion can be drawn from the experimental observation that a single strand of DNA contains 2100 dA residues and 1800 dT residues?

• A) There must have been some loss of material in the extraction because the number of dA and dT residues must be the same.
• B) This is a palindromic sequence.
• C) There must be 2100 dT and 1800 dA residues on the complementary strand.
• D) This must be prokaryotic DNA
• E) None of these

More Distant
