ANSWER -

STRUCTURE

The nucleus is a relatively large and spherical membrane-bound organelle. The nucleus itself is comprised of distinct components, and understanding their structure allows a deeper understanding of their function.

FUNCTION

The information above can be simplified into three key functions:

  • The information above can be simplified into three key functions:Cell compartmentalisation: The presence of a selectively permeable nuclear envelope separates the contents of the nucleus from that of the cytoplasm.
  • The information above can be simplified into three key functions:Cell compartmentalisation: The presence of a selectively permeable nuclear envelope separates the contents of the nucleus from that of the cytoplasm.Gene expression: Gene expression first requires transcription, which is the process by which DNA is transcribed into mRNA. As the nucleus is the site of transcription, proteins within the nucleus play a key role in regulating the process.

Before they exit the nucleus, they undergo a process known as post-transcriptional modification where molecules are added or removed from the structure.
