Here's why:
* Ribosomes are the protein synthesis machinery: They read the genetic code from messenger RNA (mRNA) and use it to assemble amino acids into proteins.
* Universality: Ribosomes are found in all living organisms, from bacteria to humans. While their structure differs slightly between eukaryotes and prokaryotes, their basic function remains the same.
It's important to note that while both eukaryotes and prokaryotes have ribosomes, the location of protein synthesis can differ.
* Prokaryotes: Ribosomes are free-floating in the cytoplasm.
* Eukaryotes: Ribosomes can be free-floating in the cytoplasm or attached to the endoplasmic reticulum (ER).
