3.5.1: Compare and contrast structure of RNA and DNA.

DNA

Both DNA and RNA contain nucleotides which contain a sugar, (deoxyribose in DNA and ribose in RNA), and a phosphate group. The DNA strand consists of two strands of nucleotide bases while the RNA strand contains one. Because the RNA structure only has one strand, the RNA cannot form a double helix structure like the DNA molecule. Also, the RNA strand  switches  uracil for thymine in the nucleotide chain.
