In prokaryotes, the processes of transcription and translation are said to be coupled, which means that: the primary transcript is immediately converted into mRNA. they are connected in space and time. the primary transcript is the mRNA. the primary transcripts carry the genetic information for the synthesis of several different proteins. several ribosomes bind to the same primary transcript.

The correct answer is ''they are connected in space and time.''

Explanation:

Transcription consists of the copying of 1 DNA chain to give an RNA chain, thanks to the complementarity of bases. The strand that is copied is known as the template strand or the transcribed strand. This chain will obviously be complementary to the RNA. A transcription unit is known as that DNA that gives rise to an RNA molecule through the transcription process. For transcription, the presence of RNA polymerase is essential, since this enzyme is in charge of synthesizing RNA, thanks to its complementarity with the template chain. RNA polymerase initiates transcription when it binds to the promoter. Transcription and translation in prokaryotes are simultaneous and from a single gene many copies of RNA can be transcribed simultaneously, which are simultaneously translated, unlike in eukaryotes where the nuclear membrane separates transcription and translation in space and time.
