1.	The transport factors that help in the transport of molecules through the nuclear pores are known as ___________(a) Nucleopherins(b) Nucleoporins(c) Karyopherins(d) KaryoporinsI have been asked this question in final exam.I want to ask this question from Nucleus topic in section Nucleus & Aerobic Respiration of Cell Biology
Answer» RIGHT answer is (c) Karyopherins Explanation: Proteins, ribosomal subunits, and some DNAs are TRANSPORTED through the pore COMPLEXES mediated by a family of transport factors KNOWN as karyopherins. Karyopherins are of two types- those that mediate movement of molecules into the NUCLEUS are called importins and those that mediate movement out of the nucleus are called exportins.
