Difference
First, the sugar in RNA is
ribose, which has one additional oxygen atom not present in DNAs sugar (deoxy-
ribose). Second, RNA has the base uracil in place of thymine. Uracil, like thymine,
forms base pairs with adenine. Third, RNA is a single strand of nucleotides, in
contrast to the double-stranded structure of DNA. This single-stranded structure
allows some types of RNA to form complex three-dimensional shapes. As a result,
some RNA molecules can catalyze reactions much as enzymes do.

Replication process
Existing molecule ->unzipping the DNA->nucleotides added->two DNA molecules formed.
Then back to the existing molecule

Dna structure
Double helix ladder shaped, 2 polynucleotide chains made of phosphates and deoxyribose, and the cross bars are made of the nitrogen bases.
