|
|
Because is to efficiently package DNA into a small volume to fit into the nucleus of a cell and protect the DNA structure and sequence.
|
|
|
Because it has a close relationship to the chromosomal matter of the cell.
|
|
|
It contains the genetic materials which is responsible for controlling and directing all the activities of the cells.
|
|
|
None of the above

Detailed explanation-1: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center. DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.
Detailed explanation-2: -The nucleus is generally considered the control center of the cell because it stores all of the genetic instructions for manufacturing proteins. Interestingly, some cells in the body, such as muscle cells, contain more than one nucleus (Figure 3.3. 2), which is known as multinucleated.
Detailed explanation-3: -Nucleus controls all the activities of a cell as it contains the genetic material. nucleoplasm and nucleolus. It controls all the activities of the cell by synthesizing rRNA and releasing into the cytoplasm for protein synthesis.
