Question

Interpret the model. This model shows that phosphate groups bond to nitrogenous bases.

A. This model shows that there is more than one kind of nitrogenous base.
B. This model shows six nucleotides bonded together.
C. This model represents two nucleic acids bonded together.
D. The 3' and 5' carbon labels are in the correct locations in the model.
E. This model shows that there is more than one kind of sugar.
F. This model shows that phosphate groups bond to sugars.

Answer 1

The model shows that phosphate groups bond to sugars to form the backbone of a nucleotide chain and indicate the presence of multiple types of nitrogenous bases. It also adheres to the standard conventions of nucleotide structure with correctly placed 3' and 5' labels.option d is correct.

Step-by-step explanation:

Based on the information provided, the model in question primarily indicates that phosphate groups bond to sugars in the structure of nucleic acids, forming the backbone of a nucleotide chain. More specifically, phosphate groups bond to the 5' carbon on the sugar of one nucleotide and the 3' carbon on the next, through phosphodiester bonds, which are covalent in nature. This constitutes the structural framework of DNA and RNA molecules.

In addition, the model would likely show that there is more than one kind of nitrogenous base, as indicated by the presence of cytosine, adenine, guanine, and thymine or uracil (depending on whether it represents DNA or RNA). Furthermore, the model could imply the existence of complementary base pairing, where adenine pairs with thymine (or uracil in RNA) and cytosine pairs with guanine, albeit the provided information does not specifically state this pairing occurs in the model. Lastly, the model likely exhibits the correct placement of the 3' and 5' carbon labels on the sugar molecules, as these are standard conventions in depicting nucleic acid structures.
