The backbones of dna and rna are

a. identical.
b. very different, made of nucleotides in dna and amino acids in rna.
c. made of alternating sugars and phosphate groups.
d. made of a chain of base pairs.

The answer is very likely C.

Explanation:

This becomes easy once we remember that DNA and RNA are not identical - which is why they have different names, RNA = 'ribo', DNA = 'deoxy.' This eliminates choice (A).  While they are different, they are not incredibly different - DNA and RNA are both made up of nucleotides - they are not however, made up of Amino acids. Amino acids are what they can code for, and subsequently create proteins during protein synthesis. This helps us eliminate (B). Finally, we know that in order for something to have base pairs it needs to be double stranded - which RNA is not. Which means that because RNA is not double stranded (its singly stranded) that the answer cannot be (D). Leaving us with the only plausible option; (C).

the answer is golgi apparatus

children tend to take more after their grandparents more than their parents. it’s the dna you received that was passed down to you somewhere in your family. maybe one of your grandparents had/has straight hair and you might have gotten it from them.
