Prokaryotic mRNA usually encodes for more than one protein while eukaryotic mRNA a single protein. Eukaryotic DNA is linear and bacterial and archaeal DNA is-linear. In prokaryotes, ribosomes attach to the mRNA and start protein synthesis even before transcription is completed. Eukaryotic mRNA, rRNA, and tRNA are all highway processed. Nuclear pore complexes control the entry and exit to and from the nucleus. They will not let mRNA exit the nucleus before it is full processed. Eukaryotic and archaeal DNA...

Problem 1 Draw a eukaryotic cell and show where DNA and mRNA are located, where proteins are synthesized and where the processes of transcription and translation take place
How does a ribosome identify mRNA for translation from the rest of the RNA species in the cell?
What is the basis of interaction between the ribosome and an mRNA molecule in eukaryotes? a. Specific base pairing between the 3' end of the 16 S rRNA in the 30S subunit and a conserved sequenced in the mRNA B. Specific interactions between ribosomal proteins and a binding protein that associates with the 5' end of the mRNA c. Specific base pairing between the 5' end of the 16S rRNA in the 30S subunit and a conserved sequenced in the...
Question 14 (2 points): Processing of a primary mRNA transcript in a eukaryotic cell DOES NOT involve: A. Excision of non-coding sequences (introns). B. Addition of the 7-methylguanosine cap at the 5'-end. C. Charging of an amino acid residue to the CCA-end. D. Joining of coding sequences (exons). E. Attachment of a long poly(A) sequence at the 3'-end.
3. What are the “translator” molecules that recognize a codon in the mRNA and deliver the correct amino acid? 6. If each amino acid was encoded by a single codon, what is the minimum number of amino-acyl tRNA synthetases required for translation? 7. Looking at the codon table, if there was a unique aminoacyl-tRNA synthetase required for each anticodon, what is the minimum required? 9. If an aminoacyl-tRNA synthetase recognized any nucleotide (purine or pyrimidine) in the 5’end of the anticodon,...
