Question

Complete translation of an mRNA to a protein can take approximately 2 minutes to complete. A cell often needs to produce many proteins to perform a task and this often has to be done on a timescale that allows for a rapid response to signals. What is one way cells speed up the production of proteins from mRNA?

Answer 1

in prokaryotic cells many ribosome binds with one m-RNA molecule and translate proteins, this situation is called polyribosome. in this way prokaryotic cells synthesize more proteins at once.

in case of eukaryotic cells, if they needs to produce lots of proteins at once , they regulate it via cell signalling, when body needs a particular protein in large scale it generates a signalling molecule that enhances gene expression, if gene expression are increased , the no. of m-RNA molecules will be increased, and that will refelect into amount of protein. in eukaryotic cells a group of cells work together and works via signalling molecule, with signalling mssenger molecule they regulate replication, transcription and translation.
