  1. Chapter 14.3 The Other RNA’s AP Biology Fall 2010

  2. tRNA • Each kind of tRNA has an anticodon that is complementary to an mRNA codon • Each tRNA also carries one specific amino acid

  3. tRNA • After the mRNA arrives in the cytoplasm, an anticodon on a tRNA bonds to the codon on the mRNA • Thus a correct amino acid is brought into place

  4. tRNA • The first two bases of the anticodon must pair up with the codon by the usual rules of base pairing (A with U and G with C) • There is some latitude in the pairing in the thrid base • Called the wobble effect

  5. Ribosome • A ribosome has two subunits • Each composed of rRNA and structural proteins • Two subunits come together only during translation

  6. Ribosome • Ribosomes are built in the nucleus • Small and large subunits come together during translation
