3. Why is it sometimes necessary to use a model that is "not to scale"?

Biology
1 answer:
joja [24]3 years ago

My answer: Because the actual thing you might be modelling might be too small or large to replicate, (for example you cannot draw a plant cell TO SCALE because it’s way too small to see with a bare eye).
And if the item is too big, you won’t be able to fit it in a small space; if you were to draw it or create it in 3D.

I hope this helps!
Sorry if the response is too short, try rewording if you need to :)

The strongly acidic nature of DNA poses a problem. Why do Watson and Crick think that the DNA "dyad", formed by hybridization of
JulsSmile [24]

Answer:

Negatively charged phosphate groups of two strands are aligned distantly from each other in a DNA double helix.

Explanation:

DNA double helix is formed when the complementary bases of two single DNA strands pair with each other. The formation of double-stranded structures places the negatively charged phosphate groups of two single DNA strands away from each other. This is because complementary base pairs are present between the sugar-phosphate backbones of two DNA strands of a double helix. The double-helical structure also concentrates the nitrogenous bases away from the surrounding watery medium. Altogether, these factors stabilize DNA dyad.
