1) DNA replication
2) Transcription
3) Translation
4) Cell division
5) Protein synthesis

Answer 1

The nucleus in eukaryotic cells has several functions, including DNA replication, transcription, translation, cell division, and protein synthesis.

Step-by-step explanation:

The nucleus in eukaryotic cells has several functions:

1. DNA replication: The nucleus is where DNA replication occurs, ensuring that the genetic material is copied accurately before cell division.
2. Transcription: Within the nucleus, genes are transcribed into mRNA, which carries the instructions for protein synthesis.
3. Translation: While translation itself occurs outside the nucleus in the cytoplasm, the nucleus is responsible for exporting mRNA molecules that were transcribed from DNA.
4. Cell division: The nucleus plays a role in cell division, as it breaks down during mitosis and meiosis when chromosomes form and cells divide.
5. Protein synthesis: The nucleus controls gene expression and regulates which proteins the cell makes, contributing to overall protein synthesis.
