Ribosomes in microbial cells mainly function to
Show Hint
Think of Ribosomes as the "Workbenches" of the cell. DNA provides the blueprints, but the Ribosomes do the actual manual labor of building proteins!

The Correct Option is A
Solution and Explanation
Concept:
Microbial cells contain specialized organelles and structures to perform life-sustaining functions. Understanding the "Central Dogma" of molecular biology—where DNA is transcribed to RNA, and RNA is translated to Protein—is key here.
Step 1: Identify the site of Translation.
Ribosomes are the cellular "factories" where the translation process occurs. They read the genetic code provided by Messenger RNA (mRNA) and assemble amino acids into long polypeptide chains.
Step 2: Evaluate other options.
• DNA Synthesis: Occurs during replication (nucleus/nucleoid).
• ATP Generation: Occurs in the mitochondria (eukaryotes) or cell membrane (prokaryotes).
• Transport: Facilitated by the cell membrane and transport proteins. Therefore, the primary and essential function of ribosomes is protein synthesis.
