WebChloroplast ribosomes, which originated from cyanobacteria, comprise a large subunit (50S) and a small subunit (30S) containing ribosomal RNAs (rRNAs) and various ribosomal proteins. Genes for many chloroplast ribosomal proteins, as well as proteins with auxiliary roles in ribosome biogenesis or functioning, reside in the nucleus. WebWhen a ribosome finds a specific RNA segment, that segment may tell the ribosome to travel to the rough endoplasmic reticulum and embed itself. ... (ROS) molecules which could seriously damage the cell. ROSs are molecules like oxygen ions or peroxides that are created as a byproduct of normal cellular metabolism, but also by radiation, tobacco ...
