- 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_forwardWhat is the start codon? What are the stop codons? Do any of them code for amino acids?arrow_forwardA frameshift mutation is caused by a: a. nucleotide substitution b. three-base insertion c. premature stop codon d. one-base insertion e. two-base deletionarrow_forward
- If 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_forwardWhat is the initiator codon in both prokaryotres and eukaryotes? What amino acid is specified by this codon? UAA, methionine UAA or UGA; Arginine AUG; arginine AUG; methioninearrow_forwardA codon that specifies the amino acid Gly undergoes a single-base substitution to become a nonsense mutation. In accord with the genetic code, is this mutation a transition or a transversion? At which position of the codon does the mutation occur?arrow_forward
- A group of 3 nucleotides codes for one amino acid. How many codons are needed to make the polypeptide that results?arrow_forwardWhich amino acid(s) have the most codons? Which amino acid(s) have the fewest codons? Can you think of a reason why multiple codons code for certain amino acids but other amino acids are coded for by very few codons?arrow_forwardThe codon chart below shows that adenine-uracil-guanine (AUG) codes for the amino acid methionine, and cytosine-adenine-guanine (CAG) codes for glutamine in humans. What do those two codons code for in carrots? A. valine and aspartic acid B. isoleucine and histidine C. methionine and glutamine D. serine and glutamic acidarrow_forward
- Is it reasonable that codons for the same amino acid have one or two nucleotides in common? Why or why not?arrow_forwardA point mutation that changes a codon specifying an amino acid into a stop codon is called aarrow_forwardHow many cases are there in which it would be possible to identify the first two nucleotides of a codon if the amino acid specified by it is known?arrow_forward
