The nuclear lamina is a netlike array of filaments on the inner side of the nuclear membrane. If a method were found that could cause the lamina to fall into disarray, what would you expect to be the most likely immediate consequence?
A) the loss of all nuclear function
B) the inability of the nucleus to divide during cell division
C) a change in the shape of the nucleus
D) closure of nuclear pores disrupting transport of materials into and out of the nucleus
E) inability of the nucleus to keep out destructive chemicals

Question

Quizplus · Accepted Answer

The nuclear lamina provides structural support to the nucleus and helps maintain its shape. If the lamina were to fall into disarray, the nucleus would lose its shape, which is likely to affect various nuclear functions, such as DNA replication and transcription, but it is unlikely to cause an immediate loss of all nuclear function, the inability of the nucleus to divide, or disruption of the nuclear pore complex. The lamina also does not play a direct role in keeping out destructive chemicals, so choice (E) is also incorrect.
