During the synthesis of the core oligosaccharide, the sugar chain is assembled on the cytoplasmic leaflet of the ER membrane, and then it is later moved to the lumen side by a flippase.
True
Cytoplasmic ribosomes and ER-bound ribosomes are structurally identical and interchangeable.
True
Ribosomal subunits are composed of rRNA that was spliced in the nucleolus, plus proteins that were synthesized in the cytoplasm and imported into the nucleus through a nuclear pore complex.
True
Ribosomes are the site of hydrolysis reactions, forming peptide bonds between amino acids.
False
DNA has a negative charge.
True
RCC1 is a GAP that resides in the nucleus. RCC1 facilitates the hydrolysis of RAN-GTP to RAN-GDP.
False
The nuclear basket extends into the nucleoplasm.
True
Which statement is true?
