RNA molecules differ from DNA molecules in that they *   a. are single stranded rather double stranded   b. contain five different bases rather than four   c. contain a greater number of nucleotide units   d. no correct response   Which of the following is definitely an incorrect codon-amino acid pairing? *   UUU-UUC and Phe-Phe

Which one of the following is a codon for amino acid valine RNA triplet code GUU? AGT CAA GUC UGA ACC

Which of the following statements is true regarding the genetic code? O One DNA base contributes to two codons O Prokaryotes use a simple one-base code, while eukaryotes use a three-base code O Codons are translated as overlapping triplets O Most amino acids are coded for by more than one codon

5) The information codon codes for a. 3; amino acids; 1 d. 3; amino acids; 3 6) 16 +1 in the mRNA is organized in units of amino acid(s). b. 4; nucleotides; 3 e. 3; nucleotides; 1 called codons. Each c. 3; nucleotides; 4

You should complete the McGraw Hill Connect Reading for Chapter 25. DNA->>> Strand (a) DNA (coding) 1. If the sequence of a DNA strand is AAT CGTCTAAGGCC, then the complementary sequence has the following sequence: 2. Complete the following diagrams illustrating.

In this picture, a tRNA is already bound to the initiator codon at the start of the mRNA strand. The anticodon sequence on this tRNA that complements the mRNA codon is A. CCC B. UAC C. CAC

Given the following RNA molecule: 5' -CUUCAGCAC- 3' a. What amino acid sequence is coded for by this molecule? b. What is the amino acid sequence if a mutation converts CAC to AAC f. What occurs when a mutation converts CAG to UAG?

A protein had the amino acids leu-gly at codons 10 and 11. A deletion of the 5’ base of the leu codon (i.e. the first base) changed the protein so that it now reads ser-ala at codons 10 and 11. The original Leu codon must have been: (hint: make use of a codon table to answer this question)   CUG AUG CUA CUC      CUU

A particular tRNA is mutated so that the amino acid attachment cannot bind with the aminoacyl-tRNA synthase. What happens when an mRNA transcript contains the codon for this TRNA? O A. The tRNA will not bind to this codon. O B. Translation stops and the protein is released. O Č. The wrong tRNA is added to the protein chain. D. Translation stops and the protein remains bound to the ribosome. vered MacBook Air 80 F3 D00 D00 F4 F2 F5 % & 23

For each amino acid added to a polypeptide which of the following must happen?   a a charged tRNA must bind at the A site of a ribosome   b a peptide bond must be made   c the mRNA must move down three bases   d all of the above
