| anticodon | group of three bases on a tRNA molecule that are complementary to mRNA codons. |
| codon | three- nucleotide sequence on mRNA that codes for a single amino acid. |
| DNA | nucleic acid that contains the sugar deoxyribose. |
| DNA polymerase | an enzyme that "proofreads" new DNA strands, helping to ensure that each molecule is nearly perfect copy of the original. |
| mRNA | RNA molecule that carries copies of instructions for the assembly oh amino acids into proteins from DNA to the rest of the cell |
| nucleotide | monomer of nucleic acids made up of: phosphate group, 5-carbon sugar ( deoxyribose or ribose), nitrogenous base. |
| promoters | region of DNA that indicates to an enzyme where to bind to make RNA. |
| RNA | single stranded nucleic acid that contains the sugar ribose. |
| rRNA | type of RNA that makes up the major part of ribosomes. |
| RNA polymerase | enzyme similar to DNA polymerase that binds to DNA and seperates the DNA strands during transcription |
| transcription | process by which part of the nucleotide sequence of DNA is copied into complementary sequence in RNA. |
