Question

The Sub-units of $80$S ribosome will be

• A. $40$S and $40$S
• B. $60$S and $40$S
• C. $60$S and $20$S
• D. $55$S and $25$S

Answer 1

The correct option is B $60$S and $40$S

Ribosomes are the site of protein synthesis. It exists in two forms the 70s and 80S. The prokaryotic cell has 70S ribosomes while the eukaryotic cell has 80S ribosomes. The 60S and 40 are subunits of eukaryotic (80S) ribosomes.

So, the correct answer is option B.
