Ansport to cytoplasm for protein synthesis (translation)
mRNA
Cell membrane
An important organelle is missing from this image of a eukaryotic cell undergoing protein synthesis. This organelle is not
surrounded by a membrane but sits in the nucleus. It produces ribosomal subunits from proteins and ribosomal RNA, which is
exported into the cell proper. It is key to the process of protein synthesis taking place at ribosomes. What is this organelle?
A)
centriole
B)
centrosome
)
mitochondria
D)
nucleolus
