Which of the following statements is false? a. GTP is an energy source during various stages of translation. b. In the ribosome, peptidyl transferase catalyzes peptide bondformation between amino acids. c. When the mRNA code UAA reaches the ribosome, there isno tRNA to bind to it. d. A long polypeptide is cut off the tRNA in the A site so its Metamino acid links to the amino acid in the P site. e. Forty-two amino acids of a protein are encoded by 126nucleotides of the mRNA.

Which statement is false: A) Each type of protein ( ex: hemoglobin vs trypsionngen) varies in the length and amino acid sequence of its peptide B) After the rpocess of transcription is complete, the mRNA that is produced will continue being tranlsated by ribosomes for the rest of the cells life. mRNA never breaks down C) A ribosome will bind to an mRNA and will translate the sequence by reading one codon at a time and adding one amino acid to the peptide chain. It will stop the translation once it encounters a stop codon D) The gene for a protein provides the information on the legth of the peptide, along w the amino acid sequence so the protein can be synthesized by a ribosome E) Once mRNA has left the nucleus, ribosomes will bind to it and will follow the instructions in its sequence to make the new protien

Refer to the DNA sequence provided: 3’ -TACTGAAGCGGCAGCCCCGCATGAGTAGACCTTACT-5’ a. What is the mRNA transcript of the anticoding strand of the DNA model? b. What is the amino acid sequence of the polypeptide chain that will be translated from the mRNA in (a)?
a. In your claim words, depict the contrast between ρ-dependent and ρ-independent end of translation in prokaryotes. b. If you have a given amino acid, can you be able to identify its RNA? Why or why not? c. How does mutation can affect the central dogma and the phenotype?
What would be the direct consequence to a cell of loss-of-function of Elongation Factor-Tu (EF-Tu)? You may select multiple answers. a. tRNAs would fail to exit the E site after giving up their amino acid. b. The error rate of translation would increase. c. The ribosome would frequently fail to identify the correct start codon and initiation of translation would become less efficient. d. There would be no pause between the entry of a tRNA into the A site and peptidyl transfer.
In this chapter you were introduced to nonsense suppressor mutations in tRNA genes. However, suppressormutations also occur in protein-coding genes. Using thetertiary structure of the β subunit of hemoglobin shownin Figure 9-3(c), explain in structural terms how a mutation could cause the loss of globin protein function. Nowexplain how a mutation at a second site in the same protein could suppress this mutation and lead to a normalor near-normal protein.
mutate all of your D-form amino acids in your peptidoglycan peptide side chains to L forms. What have just done to your peptidoglycan? • A. You prevent lysozyme from being able to work • B. You prevent NAM and NAG from linking together C. You have made it susceptible to degradation by proteases • D. You prevent it from being flipped from the cytoplasm across the plasma membrane O E. Nothing, there is no difference between the L and D forms of amino acids
The ribonucleotides C and G we're mixed together with C two times more abundant than G. The resulting RNAS we're translated in a cell free system. Give the amino acids and the relative percentages of each that would be found after the translation. Show all reasoning/calculations. Suppose that di-ribonucleotides (GC) were used to make RNA and then translated in vitro. What would the results be- explain all reasoning and explain how this information could be combined with the information in part A above to try to deduce the genetic code, assuming you didn't already know it.
a) Identify the current stage of the translation process shown in Figure 1 and name the anticodon sequence in tRNAb) State TWO immediate, main consequences when a stop codon reaches the E site.
Give typing answer with explanation and conclusion to all parts What would happen to the overall process of making proteins (transcription-translation) if the pores in the nuclear envelope were blocked? Q10. Suppose that an mRNA transcript consists of the following sequence of bases: AUGCCAGGUUAUGUCUAG. a. What sequence of amino acids would this translate to? b. Now suppose that a mutation takes place in the DNA so that twelfth base changes from U to G. How does this change the meaning of the 4th amino acid? (I.e., what does it change to?) c. Would the result be a normal protein? EXPLAIN SPECIFICALLY WHY OR WHY NOT.
