Where does transcription take place in the prokaryotic cell?

For the second questions, I don't think mRNA contains introns... as exons are the information that is going to be expressed. After all you would't want to make a protien full of junk information.

transcription, the production of a mRNA strand from a DNA template, takes place along the bacterial chromosone.

alpha/beta-tubulin are part of the cell's cytoskeleton in both prokaryoptic and eukarotic cells. In paticular, microtubles are vital for flagellum: tails that strech out from the cell and rotate to propel the cell forward.

In prokaryotic cells, they have no mechansim to spice out introns from mRNA. Eukaroyotes have spliceosomes, giant catalytic RNA structres, that splice out introns before the mRNA reaches the ribosomes.

i think its in the ribosomes, not sure tho

A prokaryotic cell doesn't have a nucleus, thus transcription occurs in the cytoplasm.

Prokaryotes DO NOT have alpha and beta tubulin. Prokaryotes were thought not to have microtubules at all, until the discovery of a tubulin-like prokaryotic protein (FtsZ). In eukaryotes, you find tubulin in the cytoplasm.

Prokaryotes do not have introns and exons; their genes are continuous. Only eukaryotes have introns and exons.
In the primary RNA transcript there are both intron and exons. While the primary RNA transcript is still in the nucleus it undergoes splicing, a process which removes introns and joins the exons in order to form a mature mRNA. This mature mRNA is exported from the nucleus to the cytosol for protein synthesis.
