Solution:
The correct answer is Ribosomes.
- Ribosomes are non-membrane bound organelles found in all cells (both eukaryotic as well as prokaryotic).
- It was discovered by Palade in 1953.
- Proteins are formed in the Ribosomes.
- A copy of the DNA is made (mRNA) and transported to a ribosome whenever a protein is produced.
- Ribosomes read the information in the mRNA and use that information to assemble amino acids into a protein.
- Several ribosomes may attach to a single mRNA and form a chain called polyribosomes or polysome
- Ribosomes are the smallest organelle in the cell.
- Ribosomes are attached to the endoplasmic reticulum.
- The eukaryotic ribosomes are also known as the 80S.
- The prokaryotic ribosomes are also known as the 70S.
- Here ‘S’ (Svedberg’s Unit) stands for the sedimentation coefficient.
