DNA/RNA

Differences and similarities between Deoxyribonucleic acid and ribonucleic acid.

?

DNA/RNA

Similarities

  • Both contain the bases Adenine, Guanine, and Cytosine
  • both made up of nucleotides which have 3 sub units joined via covalent bonds (phosphate, pentose sugar, nitrogenous base)

Differences

  • DNA contains a Deoxyribose sugar molecule, whereas, RNA contains a ribose sugar
  • RNA is single-stranded, however, DNA is double-stranded
  • RNA's fourth base is Uracil, whereas, DNA's fourth base is Thymine.

Overall comparison

DNA bases are bonded together by hydrogen bonds which makes the overall structure stableBoth DNA and RNA have  subunits of nucleotides which are joined together during condensation reactions; this produces a backbone of the nucleic acid molecule (sugar-phosphate)
