Which of the following statements is true of bacterial translation?
A
Translation occurs in the cytoplasm and is coupled with transcription.
B
Translation occurs in the nucleus and is separate from transcription.
C
Bacterial translation requires a 5' cap on mRNA for initiation.
D
Bacterial translation uses a poly-A tail for mRNA stability.
Guida verificata passo dopo passo1
Understand that bacterial cells do not have a nucleus, so all processes occur in the cytoplasm.
Recognize that in bacteria, transcription and translation are coupled, meaning they occur simultaneously in the cytoplasm.
Recall that bacterial mRNA does not have a 5' cap or a poly-A tail, which are features of eukaryotic mRNA.
Identify that the coupling of transcription and translation is a key feature of bacterial gene expression, allowing for rapid protein synthesis.
Conclude that the statement 'Translation occurs in the cytoplasm and is coupled with transcription' is true for bacterial translation.
