Chapter 10 Gene Expression and Regulation Vocabulary anticodon – sequence of 3 bases in transfer RNA that is complementary to the 3 bases of a codon of messenger RNA Barr body – inactivated X chromosome in cells of female mammals, which have 2 X chromosomes; normally appears as a dark spot in the nucleus Codon – sequence of 3 bases of messenger RNA that specifies a particular amino acid to be incorporated into a protein; certain codons also signal the beginning or end of protein synthesis deletion mutation – mutation in which 1 or more pairs of nucleotides are removed from a gene exon – segment of DNA in a eukaryotic gene that codes for amino acids in a protein gene – unit of heredity that encodes the information needed to specify the amino acid sequence of proteins and hence particular traits; functional segment of DNA located at a particular place on a chromosome genetic code – collection of codons of mRNA, each of which directs the incorporation of a particular amino acid into a protein during protein synthesis gene expression - insertion mutation – mutation in which 1 or more pairs of nucleotides are inserted onto a gene intron – segment of DNA in a eukaryotic gene that does not code for amino acids in a protein messenger RNA
