1. The Other RNAs AP Biology Fall 2010

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

3. 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

5. 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

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

7. Ribosomes are built in the nucleus Small and large subunits come together during translation
