E)spliceosome

Question

Quizplus · Accepted Answer

Proteasomes are responsible for degrading misfolded proteins in the cytoplasm. These are large protein complexes that identify and degrade proteins marked for destruction by ubiquitin. Ubiquitin is a small protein that is attached to misfolded proteins, targeting them for destruction by the proteasome. Polysomes and polyribosomes are terms used interchangeably to refer to multiple ribosomes attached to a single mRNA molecule involved in protein synthesis. Peroxisomes are organelles responsible for detoxifying harmful substances in the cell. The spliceosome is a complex of RNA and proteins that removes introns from pre-mRNA.
