Document Summary
Biology 1p03 chapter 12 key terms, learning goals, and review questions. Anticodon a sequence of three bases in transfer rna that is complementary to the three bases of a codon on messenger rna. Barr body a condensed, inactivated x chromosome in the allele of female mammals that have two x chromosomes. Codon a sequence of three bases in 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 a mutation in which one or more pairs of nucleotides are removed from a gene. Exon a segment of dna in a eukaryotic gene that codes for amino acids in a protein; see also intron. Genetic code the collection of codons of mrna, each of which directs the incorporation of a particular amino acid into a protein during protein synthesis or causes protein synthesis to start or stop.

- Refer to Exercise 4. Write the letters for the base sequence ofmRNA in the spaces below DNA. Note that the order is reversed;start with the 3Ć¢ĀĀ end of the DNA strand and the 5Ć¢ĀĀ end of the mRNAstrand. Transcription is DNA to mRNA. Note RNA contains Uracilinstead of Thymine; There is no thymine in RNA.
