- A certain mRNA strand has the following nucleotide sequence: 5AUGACGUAUAACUUU3 What is the anticodon for each codon? What is the amino acid sequence of the polypeptide? (Use Figure 13-5 to help answer this question.) Figure 13-5 The genetic code The genetic code specifies all possible combinations of the three bases that compose codons in mRNA. Of the 64 possible codons, 61 specify amino acids (see Figure 3-17 for an explanation of abbreviations). The codon AUG specifies the amino acid methionine and also signals the ribosome to initiate translation (start). Three codonsUAA, UGA, and UAGdo not specify amino acids; they terminate polypeptide synthesis (stop).arrow_forwardIf the genetic code uses triplets, how many different amino acids can be coded by a repeating RNA polymer composed of UA and UC (UAUCUAUCUAUC ...)? a. one b. two c. three d. four e. fivearrow_forwardGive features of genetic code.arrow_forward
- RNA has many functions in a cell. Besides mRNA, which carries information from the genome to the translation machinery, and rRNA, which is part of ribosomes and catalyzes the formation of peptide bonds, name three other types of RNA and describe the function of each.arrow_forwardDefine the following terms: genetic code, codon, and anticodon. What is the relationship among the bases in DNA, the codons of mRNA, and the anticodons of tRNA?arrow_forwardUse this genetic code table for some of the questions ahead. You do not need to memorize the code, except for the start codon (AUG = Met) and the stop codons (UAA, UAG, UGA). Which of the following statements about the genetic code is correct? A) All codons specify more than one amino acid. B) The genetic code is redundant. C) All amino acids are specified by more than one codon. D) All codons specify an amino acid.arrow_forward
