Webb29 okt. 2024 · Do Ribosomes Make A Protein Prokaryotic Or Eukaryotic? Ribosomes are composed of both ribosomal proteins and ribosomal RNA (rRNA). Ribosomes are responsible for roughly 40% of the protein in prokaryotes and 60% of the RNA in prokaryotes. In eukaryotes, ribosomes are half protein and half RNA. WebbIV.A Ribosome Structure. Ribosomes are high-molecular-weight complexes of RNA (rRNA) and proteins (Table I ), and the electron-dense particles are easily visualized by electron microscopy. Ribosomes from various sources (prokaryotes, eukaryotic cytoplasm, mitochondria, chloroplasts, and kinetoplasts) vary in size from 20 to 30 nm in diameter ...

WebbDescribe translation in eukaryotes. Translation is the process by which the genetic information carried by mRNA is used to synthesize a protein. In eukaryotes, translation occurs in the cytoplasm and involves three main steps: initiation, elongation, and termination.

Oppositely, 80-S ribosomes are typically a part of eukaryotic cells. The 70-S ribosome in prokaryotic cells originates within the cell cytoplasm. In contrast, the synthesis of 80-S ribosomes is in the cell nucleolus.
