Choose the type of RNA that correctly completes each statement. Each answer is used once. A ( n ) base sequence specifies the amino acid sequence of a polypeptide. Each type of carries a specific amino acid to ribosomes to be added to polypeptides. Ribosomes are composed of ribosomal proteins and Question 18 Which of these is NOT a correct statement about the genetic code? In general, prokaryotes and eukaryotes use the same genetic code to make proteins. 61 codons specify the 20 types of amino acids. A codon is a sequence of three bases. Each type of amino acid is only specified by one codon. Question 19 Which of these is a correct statement about translation in prokaryotes? An RNA molecule can only include one protein-coding sequence. Ribosomes move along an RNA in the 3 ' to 5 direction.
