Question
Chapter 29, Problem 15P
Interpretation Introduction
Interpretation:
Anexplanation of chromosome fusion in cells lacking telomerase enzyme needs to be proposed.
Concept introduction:
Short repeated sequences that are rich in G base and are present on to the ends of chromosomes are known as telomer. They are added by the enzyme telomerase at the end of the chromosome in order to protect it. Generally, the activity of telomerase is maintained in germline cells.

The function of FG-nucleoporins within the nuclear pore complex is to: shield large, hydrophilic, unchaperoned proteins from entering the nucleus. prevent small, hydrophobic proteins from entering the nucleus. cleave the nuclear localization sequence (NLS) from the protein to be imported. aid GAP in the hydrolysis of GTP to GDP. All of the above. Question 5, Ultimately, the entire process of nuclear protein import is driven by: the concentration gradient of the imported protein across the nuclear membrane. the localization of Ran FG-nucleoporins in the nuclear pore complex (NPC) GTP hydrolysis None of the above Question 6 During the process of nuclear import, a GEF works in the: cytoplasm to exchange GTP for the GDP bound to Ran cytoplasm to use GTP to release Ran from importin nucleus to exchange GTP for the GDP bound to Ran nucleus to activate the intrinsic GTPase activity of Ranarrow_forward
