Ribosomes in prokaryotes is of 70 S type. What does ‘s’ stands for and what does it measure?

Explanation

### Step-by-Step Solution:

1. **Understanding Ribosomes**: Ribosomes are essential cellular structures responsible for protein synthesis. They are found in both prokaryotic and eukaryotic cells, but they differ in size.

2. **Identifying Ribosome Types**: In prokaryotic cells, ribosomes are classified as 70S, while in eukaryotic cells, they are classified as 80S. The 'S' in these classifications is crucial for understanding ribosome characteristics.

3. **Defining 'S'**: The 'S' stands for the Swedberg unit. This unit is named after Theodor Svedberg, a Swedish chemist who contributed to the study of colloidal solutions and sedimentation.
