Textbook Question

Using the genetic code (Table 10.1), list the order of amino acids encoded by the following mRNA nucleotides: CAACGCAUUUUG.

Verified step by step guidance

Identify the mRNA sequence: CAACGCAUUUUG.

Divide the mRNA sequence into codons (groups of three nucleotides): CAA, CGC, AUU, UUG.

Use the genetic code table to find the amino acid for each codon: CAA, CGC, AUU, UUG.

Match each codon to its corresponding amino acid using the table: CAA -> Glutamine (gln), CGC -> Arginine (arg), AUU -> Isoleucine (ile), UUG -> Leucine (leu).

List the order of amino acids encoded by the mRNA sequence: Glutamine, Arginine, Isoleucine, Leucine.

Textbook Question

Which of the following describes the experimental strategy that was used to decipher the genetic code? a. comparing the amino acid sequences of proteins with the base sequence of their genes b. analyzing the sequence of RNAs produced from known DNA sequences c. analyzing mutants that changed the code d. examining the polypeptides produced when RNAs with particular sequences were translated

For each of these statements about the genetic code, select True or False. a. T/F Wobble pairing accounts for the redundancy of the genetic code. b. T/F There are 64 different tRNAs that read the 64 possible codons. c. T/F All possible codons are used, but not all codons specify an amino acid. d. T/F Some codons are recognized by proteins, not by tRNAs.

A minimal genetic code requires only 21 codons—one for each amino acid, and one for a stop signal. Given this, what advantage might be offered by having a code with 64 codons?

Textbook Question

Draw a hypothetical metabolic pathway in Neurospora crassa composed of five substrates, five enzymes, and a product called nirvana. Number the substrates 1–5, and label the enzymes A–E, in order. (For instance, enzyme A catalyzes the reaction between substrates 1 and 2.) (b) Suppose a mutant strain can survive if substrate 5 is added to the growth medium, but it cannot grow if substrates 1, 2, 3, or 4 are added. Which enzyme in the pathway is affected in this mutant?

How many amino acids would be encoded in the sequence 5′-AUGUUACGGAAU-3′ by a non-overlapping and a maximally overlapping triplet code? a. 4 (non-overlapping) and 16 (overlapping) b. 4 and 12 c. 4 and 10 d. 12 and 4

Textbook Question

Researchers compared the amino acid sequences of the transport protein in zebrafish, puffer fish, mice, and humans. They found many stretches with identical sequences in all four species. Does this mean that the corresponding mRNA base sequences are also the same in these four species? Explain why or why not.
