Question

The Eukaryotic nucleolus is a region within the nucleus where ribonucleoproteins assembly takes place. It is not another name for the spliceosome, nor the regions in the nucleus where the heterochromatin regions of chromosome reside. It is also not a region of the nucleus kept deliberately free of reactions so as not to interfere with chromosomes. What is the Eukaryotic nucleolus?

1) Region within the nucleus where ribonucleoproteins assembly takes place
2) Another name for the spliceosome
3) Regions in the nucleus where the heterochromatin regions of chromosome reside
4) Region of the nucleus kept deliberately free of reactions so it is not to interfere with chromosomes

Answer 1

The nucleolus is a region within the nucleus of eukaryotic cells where ribonucleoproteins assembly takes place and RNA necessary for ribosome construction is manufactured. It is responsible for ribosome synthesis and subunit assembly, and is distinct from other structures within the nucleus.

Step-by-step explanation:

The nucleolus is a region within the nucleus of eukaryotic cells where ribonucleoproteins assembly takes place. It is responsible for manufacturing the RNA necessary for the construction of ribosomes. The ribosomal subunits are then transported out of the nucleus through the nuclear pores.

The nucleolus is not another name for the spliceosome or the regions in the nucleus where the heterochromatin regions of chromosomes reside. Additionally, it is not a region of the nucleus kept deliberately free of reactions to avoid interfering with chromosomes.
