Page 2: The Other RNAs AP Biology Fall 2010. Each kind of tRNA has an anticodon that is complementary to an mRNA codon Each tRNA also carries one specific amino.

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

Page 3: The Other RNAs AP Biology Fall 2010. Each kind of tRNA has an anticodon that is complementary to an mRNA codon Each tRNA also carries one specific amino.

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

Page 5: The Other RNAs AP Biology Fall 2010. Each kind of tRNA has an anticodon that is complementary to an mRNA codon Each tRNA also carries one specific amino.

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

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

translation

Ribosomes are built in the nucleus Small and large subunits come together

during translation
