Question
________ are single-walled dense spherical bodies composed mainly of RNA.
- Ribosomes
- Lysosomes
- Plastids
- Nucleus
Hint:
Ribosomes are single-walled dense spherical bodies composer mainly of RNA.
The correct answer is: Ribosomes
- The ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell.
- The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.
