Question

What are the two types of ribosomes?

• A. The 70S and 60S
• B. The 70S and 80S
• C. The 80S and 60S
• D. The 80S and 50S

Answer 1

The correct option is B

The 70S and 80S

The correct option is B.

Explanation of correct option:

1. An intercellular composition formed of both protein and RNA (ribonucleic acid) is known as a ribosome.
2. It is the site of the synthesis of proteins within the cell.
3. The 80S ribosomes are found in the eukaryotes, which are further formed by 60S and 40S subunits.
4. The 80S ribosomes are found within the cytoplasm or attached to the endoplasmic reticulum.
5. It assists in the process of translation of mRNA (messenger ribonucleic acid) into amino acids.
6. In prokaryotes, the 70S ribosomes are commonly found.
7. They are further produced of two subunits, i.e. the 30S and 50S.
8. The 70S ribosomes are found freely within the cytoplasm of prokaryotes.
9. It assists in the production of proteins within the cells of prokaryotes.

Final answer: The two types of ribosomes are the 70S and 80S.
