Question

use the questions below to see how well you understand the relationship between the dna of an organism and its traits.
which of the following are correct statements regarding the dna molecule?
choose all that apply
a the adenine (a) nucleotide on one strand always pairs with a guanine (g) nucleotide on the other strand.
b the information is contained within the nucleotides of the dna.
c it is a double helix.
d the two dna strands are oriented in an anti-parallel configuration.

Explanation:

• Option a: Incorrect. Adenine (A) pairs with thymine (T), while guanine (G) pairs with cytosine (C) in DNA.
• Option b: Correct. Genetic information is stored in the specific sequence of nucleotides (A, T, C, G) in DNA.
• Option c: Correct. The structure of DNA is a double-stranded helix, as described by Watson and Crick.
• Option d: Correct. The two strands of DNA run in opposite (anti-parallel) directions, with one strand oriented 5' to 3' and the other 3' to 5'.

Answer:

b. The information is contained within the nucleotides of the DNA.
c. It is a double helix.
d. The two DNA strands are oriented in an anti-parallel configuration.
