Which is NOT a way RNA differs from DNA?
|
|
Contains a single strand
|
|
|
Contains Uracil (U) instead of Thymine (T)
|
|
|
Contains the sugar ribose
|
|
|
Contains an extra nitrogen base
|
Explanation:
Detailed explanation-1: -Explanation: RNA and DNA major difference is nitrogenous bases and sugars. RNA has sugar ribose and DNA has deoxyribose and only one nitrogenous base-pair varies in DNA and RNA i.e., thymine is present in DNA and Uracil in RNA.
Detailed explanation-2: -The correct answer is (C) Ribonucleotides contain a phosphate group.
Detailed explanation-3: -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-4: -⇒ Thymine is present in DNA but not in RNA.
