DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is NOT a difference between RNA and DNA?
A
RNA is single stranded and DNA is double stranded
B
RNA contains Uracil, DNA doesn’t
C
DNA has to stay in the nucleus, RNA doesn’t
D
RNA has extra proteins attached and DNA doesn’t
Explanation: 

Detailed explanation-1: -The thing that is not a difference is C. So DNA and RNA are both made up of nucleotides. Nucleotides. It’s something like this as a phosphate group.

Detailed explanation-2: -There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

Detailed explanation-3: -Summary of Differences Between DNA and RNA DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans.

Detailed explanation-4: -So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.
