3.4.1 genetic code

• gene: a section of DNA that codes for a polypeptide.
• Locus: position of a gene on a chromosome.
• Amino acid: a monomer of protein
• Degenerate code: multiple codons for the same amino acid.
• Triplet: a sequence of 3 bases.
• Universal: same for all species.
• Introns: non-coding regions of DNA.
• Exons: coding regions of DNA (genes)
• Codon: a sequence of 3 RNA bases that codes for an amino acid.
• genome: the entire set of genetic material in an organism, including all the genes and the DNA that controls them
• proteome: all proteins in a cell or organism, including all proteins that are expressed
• what are the 2 types of RNA?

  messenger RNA (mRNA) and transfer RNA (tRNA)
• anticodon: the sequence of bases on the tRNA that complement the codon on the mRNA
