Question

Compare DNA and RNA by addressing the number of strands, sugar used, nucleotide bases used, typical location in the cell, and function or role.

Answer 1

(STRAND)

DNA has two strands arranged in a double helix. RNA consists of a single strand

(SUGAR)

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.

(NUCLEOTIDE)

A DNA nucleotide contains deoxyribose sugar, whereas an RNA contains the sugar ribose in every nucleotide. The nitrogenous bases in DNA can be adenine, guanine, cytosine, and thymine. Unlike DNA, RNA contains a uracil nitrogenous base instead of thymine.

(LOCATION)

DNA is located in the nucleus of a cell and in the mitochondria. Meanwhile, RNA is found in the cytoplasm, nucleus, and also in the ribosomes

(FUNCTION)

DNA stores genetic information for the cell, whereas RNA codes for amino acids and acts as a messenger between DNA molecules and the ribosomes.
