Question

rRNA present in 50 S subunit of ribosome is

• A. 23 S
• B. 5 S
• C. Both A and B
• D. 23 S, 5.8 S and 5 S

Answer 1

Answer: (C)

Both A and B

• In prokaryotes with 70S ribosomes consists of 30S subunit and a large 50S subunit.
  
• The large subunit (the 50S) is made up of a 5S RNA subunit with 120 nucleotides, a 23S RNA subunit with 2900 nucleotides and 31 proteins.
• So, the correct answer is 'Both A and B'.
