A codon in the genetic code consists of:: (A) One molecule of charged-tRNA, (B) A Shine-Dalgarno sequence, (C) Three consecutive nucleotides, (D) Two complementary base pairs
Answer is C. A codon is a triplet sequence of bases. The tRNA molecule contains an anticodon. The Shine-Dalgarno sequence is found in the 23S prokaryotic ribosomal RNA. A codon is on the same strand of DNA or mRNA.
