Concept explainers
Number the following steps of protein synthesis in the order in which they occur, starting with 1 and ending with 9.
a._____The stop codon is reached, and the polypeptide is released.
b._____The small ribosomal subunit finds the start codon, and the large ribosomal subunit joins.
c._____The end of the gene is reached, and the pre-mRNA is released and then edited.
d._____The transcription factor binds the promoter.
e._____The protein is folded and modified to become functional.
f._____RNA polymerase builds the mRNA transcript.
g._____mRNA and initiator tRNA bind the small ribosomal subunit.
h._____New tRNAs are brought into the A site successively, and the peptide chain of the tRNA in the P site is joined to the amino acid of the tRNA in the A site.
i._____mRNA exits the nucleus via a nuclear pore.

- Each of the following statements about protein synthesis is false.Correct each to make a true statement. a. In a gene, each nucleotide specifies one amino acid in a protein sequence. b. A transcription factor must bind to the promoter region of a gene before the enzyme DNA synthetase is able to bind and begin transcription. c. The enzyme RNA polymerase builds a strand of transfer RNA, whose codons are complementary to DNA’s triplets. d. Proteins destined for secretion from the cell enter the nucleus after translation, to be folded and modified. e. During translation, amino acids are delivered by the messenger RNA transcriparrow_forwardSequence the following steps in protein synthesis from first to last. Write only the numbers (1-6) on space provided for; ____a. transcription ____b. tRNA amino acid ____c. amino acids separate from tRNA ____d. polypeptide chain assembled ____e. mRNA links to ribosome ____f. stop codon encountered in mRNAarrow_forwardComplete the phrases with the correct word or words. The task is to match the lettered items with the correct numbered items. Appearing below is a list of lettered items. Following that is a list of numbered items. Each numbered item is followed by a drop-down. Select the letter in the drop down that best matches the numbered item with the lettered alternatives. a. methionine b. ribosome c. codon d. AUG e. UAC The mRNA moves out of the nucleus and attaches to a The first codon of an mRNA molecule is always As soon as the first codon is in place, a tRNA molecule arrives with the anti-codon The first tRNA to arrive always carries the amino acid called, The ribosome scoots along the mRNA to read the nextarrow_forward
- a. Give the sequence of mRNA that would be transcribed off of the bottom strand and label its 5' and 3' ends. b. translate this RNA sequence in 1a into a protein sequence c. Give the sequence of mRNA that would be transcribed off of the top strand and label its 5' and 3' ends. d. Translate this RNA sequence in 1c into a protein sequencearrow_forwardIndicate the phase of protein synthesis during which each of the following processes occurs: a. A ribosomal subunit binds to a messenger RNA. b. The polypeptide is actually synthesized. c. The ribosome moves along the codon sequence. d. The ribosome dissociates into its subunits.arrow_forwardPlease consider the figure below. a. Give the name of the process illustrated in the figure. b. If this is part of the elongation stage, explain what is going to happen next. Use the labels, A, B and/or C to answer the question. c. What type of enzyme is involved in the process described in (b)? d. What terminus of the protein is represented by label A?arrow_forward
- Which of the following statements are NOT true? A. Replication is the process of making DNA and takes place in the nucleus of prokaryotic cells. B. Translation produces a polypeptide that may require additional processing to become a functional protein C. Transcription starts at the promoter of eukaryotic cells and scans until reaches the start codon. D. Splicing results in exons being put together and introns being removedarrow_forwardArrange the statements in their proper order by writing the corresponding letter (e.g. A) for each statement in the space provided below. A. The single-stranded RNA would complement the target RNA. B. Gene expression is inactivated once the mRNA is no longer accessible for translation. C. The risk-induced silencing complex which is composed of RNA and protein subunits is formed. D. Double-stranded, non-coding RNA is cleaved by Dicer. E. The mRNA can be cleaved or remain bound by the RISC. 1. 2. 3. 4. 5.arrow_forwardThe fourth codon in an mRNA sequence is GGG, which specifies glycine. If we assume that no amino acids are removed from the polypeptide, which of the following statements is correct? a. The third amino acid from the N-terminus is glycine. b. The fourth amino acid from the N-terminus is glycine. c. The third amino acid from the C-terminus is glycine. d. The fourth amino acid from the C-terminus is glycine.arrow_forward
- Which of the following BEST describes the characteristics and function of siRNA? A. a short strand of RNA that can complement and inactivate a sequence of mRNA B. a short strand of RNA that can act as a transcription factor to initiate transcription C. a strand of DNA that can bind to and inactivate an mRNA sequence D. a tRNA that is not able to attach to a ribosome and therefore inhibits the process of translationarrow_forward3. Given the following DNA molecule: 3' T 5' cG G T АА А АСТ А | | | | | | | | | | | АT G C САТ ТТТGА 5' - A 3.arrow_forwardThe fourth codon in an mRNA is GGG, which specifies glycine.
