Could eukaryotic ribosomes accurately translate an mRNA from bacteria? Why or Why not?

Homework Answers

Answer #1

No, eukaryotic ribosomes can not translate bacterial mRNA

Reason-

Bacteria uses formyl methionine as a start codon but eukaryotes uses only methionine and the eukaryotic ribosome can't add firmyl methionine at P site.

Eukaryotic mRNA is capped at 5' end while prokaryotic mRNA. Does not contains the cap at 5' end. This is the cap of the eukaryotic mRNA at which ribosome binds. If cap is not present ribosome can not bind at mRNA.

Bacterial mRNA contain Kozak sequence while eukaryotic mRNA contains Shine-Dalgarno sequence.  Eukaryotic ribosome are specific for Shine-Dalgarno sequence.

1. Select all the of the statements below that apply to both eukaryotic and bacterial gene expression? Bacteria and eukaryotes can have 70S ribosomes. Bacteria and eukarytoes may have genes organized and regulated within operons. Bacteria and eukaryotes have 70S ribosomes in their cytoplasm. Initiation of translation in bacteria and eukaryotes occurs when the ribosomal subunit binds to the 5' guanine cap. Bacterial and eukaryotic mRNA is modified prior to translation.

In eukaryotic cells, when ribosomes are translating polypeptides they can be either free in the cytosol or associated with endoplasmic reticulum (ER). What determines their location? a. Two types of ribosomes have different compositions that determine their location. b. The types of mRNA that ribosomes are translating determine their location c. The site of ribosomes assembly determines their location. d. Some stochastic events determine their location e. The polypeptide transport machinery determines their location on ER.?

Streptomycin (an antibiotic) binds to the small ribosomal subunit of bacteria (but not to the ribosomes of the host cells infected by bacteria). The result is the misreading of bacterial mRNA and the breakup of polysomes. What process is being affected, and how does this kill the bacterial cells? Describe the steps of this process in normal cells.

Why do bacterial mRNAs, but not eukaryotic mRNAs, require a Shine-Dalgarno sequence? A. mRNA splicing would remove Shine-Dalgarno sequences. B. Eukaryotic mRNAs must exit the nucleus. C. Bacterial mRNAs are shorter lived. D. The eukaryotic poly-A tail serves the same function. E. Bacterial mRNAs are often polycistronic.

Why would antibiotics that affect the ribosome kill bacteria without harming their host? A. Antibiotics form different types of bonds with prokaryotic proteins and eukaryotic proteins, so only the interactions with prokaryotic proteins affect ribosome function. B. Prokaryotic ribosomes have a different structure than eukaryotic ribosomes, so antibiotics that bind to one cannot bind to the other. C.Eukaryotes are more complex than prokaryotes. D. Fungi do not need to kill eukaryotes, only prokaryotes.

1. Why can't transcription and translation of an mRNA occur at the same time in eukaryotes like it does in prokaryotes? In bacteria, translation of an mRNA can begin before its transcription is complete. mRNA synthesis begins at the 5' end and moves toward the 3' end.  After the 5' end is made, ribosomes can bind and begin translation. This coupling of transcription and translation does not occur in eukaryotes. Why not? 2. There is an amino acid that transfers its...
