Terms to Know
  • Codons

    Sections of 3 nucleotides that code for an amino acid.

  • Exons

    Sections of RNA that code for proteins.

  • Genetic Code

    Information stored in the nucleotide sequence of DNA that forms our genes.

  • Protein Synthesis

    The formation of proteins by using information stored in DNA to form proteins.

  • RNA Polymerases

    An enzyme used to form a single strand of RNA from a DNA strand.

  • Regulatory Proteins

    Proteins that can stop or speed up transcription.

  • Start Codon

    A codon used to signal the start of an amino acid sequence on a strand of mRNA.

  • Stop Codon

    A codon used to signal the stop of an amino acid sequence on a strand of mRNA.

  • Transcription

    The process of converting DNA into RNA.

  • mRNA

    Messenger RNA that is used to convert RNA code into protein.

  • rRNA

    Ribosomal RNA is used to produce the structure of ribosomes.

  • tRNA

    Transfer RNA that is used to bind ribosomes to the start codon of a nucleotide chain in order for translation to occur.
