Cytoplasmic protein synthesis
WebCycloheximide, an inhibitor of cytoplasmic translation, induced a rapid reduction of 70-80% in levels of mRNA for the chloroplast elongation factor Tu (tufA) in asynchronously growing Chlamydomonas. This effect was shown to be mainly transcriptional, and not restricted to tufA, as transcription of o …

WebThe rough endoplasmic reticulum (rough ER) gets its name from the bumpy ribosomes attached to its cytoplasmic surface. As these ribosomes make proteins, they feed the newly forming protein chains into the lumen. Some are transferred fully into the ER and float inside, while others are anchored in the membrane.
