Match the following nuclear locations to its function

Question

i. Nuclear pore complexes _________
ii. Nuclear lamina _________
iii. Nucleolus _________
iv. Nuclear Envelope _________

a. Matrix of proteins that provide nuclear shape and structure

b. Processing of ribosomes

c. Separate the nucleus from the cytoplasm

d. Allow for transport between the nucleus and cytoplasm

Accepted Answer

Okay. So this practice problem is a matching practice problem. And it says match the following nuclear locations to its function. So, let's just go through these together and see if we can figure it out as we go. So, the first one says nuclear pore complexes. So, what are nuclear pore complexes? Remember, those are the groups of proteins that allow, and that connect the nucleoplasm and the cytosol. So, do any of these match that description? Right. So, looking at these, it would be d and allows for transport between the nucleus and the cytoplasm. Now, the second one is the nuclear lamina. So, do you remember what is the nuclear lamina? Right. So that is the meshwork of proteins that provide shape and structure to the nucleus, and they kind of reside right under the nuclear envelope. And so, we're looking at these answers. The first one that comes shows up is a, which is, the matrix of proteins that provide nuclear shape and structure. So, 3 says, nucleolus. So, do we remember what the nucleolus does? Right. That s the place of ribosome formation. So, out of the two choices left, it s very clearly B. And then finally, the last one has to be C, it s the only answer left. But, it s also the nuclear envelope, which is responsible for separating the nucleus from the cytoplasm, which matches here. So, DABC, which matches here. So, DABC. So, those are the nuclear, locations and their functions. So, let's move on.
