• DNA means

  deoxyribonucleic acid
• each nucleotide is made up of a sugar called deoxyribose
• deoxyribose is almost the same but lacks one oxygen atom
• the sequence of bases in DNA forms the genetic code
• triplet code: the amino acids are joined together in the correct sequence to make part of a protein.
• decoding DNA > mRNA > tRNA > amino acid
• both molecules may be represented by the symbol Pentagone.
