DNA and RNA molecules are similar in that they both contain (1) nucleotides (2) a double helix (3) deoxyribose sugars (4) thymine

How are DNA and RNA different?In living cells, RNA is usually a double-stranded molecule, while DNA can often be single-stranded.DNA contains phosphate, while RNA does not.DNA contains the sugar dextrose, while RNA contains the sugar ribose.DNA contains the bases A, G, C, and T; RNA contains the bases A, G, C, and U.

a. In what ways are the structures of RNA and DNA alike, and in what ways are they different?

DNA differs from RNA because, unlike RNA,Multiple ChoiceDNA contains uracil.DNA contains thymine.DNA can catalyze some chemical reactions.DNA is usually single-stranded in cells.DNA contains ribose.

Give three structural differences between DNA and RNA

10. Which of the following is not a difference between RNA and DNA?a. RNA has uracil; DNA has thymine.b. RNA has ribose; DNA has deoxyribose.c. RNA has five bases; DNA has four.d. RNA is a single polynucleotide strand; DNA is a double strand.e. RNA is relatively smaller than human chromosomal DNA.
