Question

1. look at the model. then, choose the best answer. dna double helix what is the limitation of this model? the exact length of a dna strand found in humans colors identifying different parts of the dna structure the overall shape of dna as being helical in nature types of dna building blocks (adenine, guanine, etc.) used

Explanation:

This model is a simplified representation. It cannot show the exact length of a human DNA strand as human DNA is extremely long and complex. The colors are just for identification, the helical shape is a correct general - feature, and the types of building blocks are accurately represented.

Answer:

the exact length of a DNA strand found in humans
