Question

Microbiologists describe the processes of transcription and translation as 'coupled' in bacteria. This term indicates that a bacterial mRNA can be undergoing transcription at the same moment it is also undergoing translation.

How is coupling of transcription and translation possible in bacteria?

Hi, everyone. Let's take a look at this practice problem together. Which of the following statements best describes the reason for faster rate of protein synthesis in bacteria. The answer options are a lesser enzymes needed. B they thrive at higher temperatures. C lack of compartmentalization and D both A N C. So let's talk about option A that lesser enzymes are needed in bacteria for translation. And while this statement may be, may be true, it is not the only factor of translation rate. Now, translation rate is influenced by things such as transcription rate, ribosome numbers and translation modulation. So option A is incorrect. Option B that bacteria thrive at higher temperatures also does not relate to the rate of translation. These higher temperatures can increase reaction kinetics but it could result in negative consequences, four protein stability and structure. So it can negatively affect protein synthesis. So option B is also incorrect. The correct answer is option C the lack of compartmentalization, this results in faster translation and it's more efficient because there's not as many obstacles. So the correct answer is option C lack of compartmentalization. All right, everyone. I hope you found this helpful and I'll see you soon for the next practice problem.
