Question

Assembly of 60 S and 40 S subunits of ribosome produces

• A. 80 S
• B. 70 S
• C. 50 S
• D. 100 S

Answer 1

Answer: (A)

80 S

• The assembly of 60 S and 40 S subunits of ribosome produces 80S ribosomes.
  
• It is the characteristic of a eukaryotic cell.
• 80S ribosomes are found in the nucleus of a eukaryotic cell.
• The smaller subunit (40S) has an 18S RNA with 1900 nucleotides and 33 proteins.
• The larger subunit (60S) has 5S RNA with 120 nucleotides, 28S RNA with 4700 nucleotides, a 5.8S RNA with 160 nucleotides subunits and 46 proteins.
• So, the correct answer is '80 S'.
