In DNA molecules,_____.
A)the nucleotides are arranged in a linear, unbranched pattern
B)the nitrogenous bases are found on the outside of the molecule
C)the phosphate-sugar pattern runs the same way on each DNA strand
D)the backbone is internal to the molecule
E)the pairing of bases is non-specific

Question

Quizplus · Accepted Answer

The nucleotides in DNA are arranged in a linear, unbranched pattern, forming a double helix structure.

Answer: C
 The phosphate-sugar pattern runs in the same direction (5' to 3') on each DNA strand, which is important for the complementary base pairing and replication of DNA.

Answer: D
 The phosphate-sugar backbone of DNA is on the inside of the molecule, while the nitrogenous bases are on the outside and facing towards each other in the middle.

Therefore, the correct answer is A and C.
