Which aspects of the structure of DNA are explained by the Watson and Crick model?
A
The triple helix structure and identical base pairing
B
The double helix formation and complementary base pairing
C
The presence of ribose sugar in the backbone
D
The linear arrangement of amino acids
Verified step by step guidance1
Understand that the Watson and Crick model of DNA describes the structure as a double helix, which consists of two strands that wind around each other.
Recognize that the model explains complementary base pairing, where adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G). This is crucial for the replication and transcription processes.
Note that the Watson and Crick model does not describe a triple helix structure; it specifically identifies the double helix formation.
Identify that the backbone of DNA in the Watson and Crick model is composed of deoxyribose sugar, not ribose sugar, which is found in RNA.
Understand that the linear arrangement of amino acids is related to proteins, not directly to the structure of DNA as described by Watson and Crick.
