Why is it that bacterial ribosomes can begin translation bef

Why is it that bacterial ribosomes can begin translation before mRNA synthesis is completed, but eukaryotic ribosomes cannot?

a. mRNA splicing occurs very quickly in prokaryotic cells.

b. In prokaryotes, transcription and translation take place in the cytoplasm.

c. Prokaryotic mRNAs are elongated differently from eukaryotic mRNAs.

d. Prokaryotic mRNAs are synthesized with ribosomes attached.

Solution

Answer is b. In prokaryotic organisms there is no nuclei, so both transcription and translation occur in the same place that is Cytosol. Moreover, no post transcriptional modifications like caping and Tailing. Due to this the half life of Prokaryotic m-RNA is too small. Due to these two reasons, in prokaryotic organisms, translation start, before completion of transcription
