DNA in the nucleus of eukaryotic cells is collected into a chromatin.
A chromatin is a complex of nucleic acids (DNA or RNA) and proteins called histones which condense to form a chromosome during cell division.
In eukaryotic cells, it is found within the cell nucleus while in prokaryotes, it is found inside the nucleoid .
Its functions are;
1. to package DNA into a smaller volume to fit in the cell.
2. strengthen the DNA to allow mitosis and meiosis.
3. acts as a mechanism to control expression
The chromatin is easily recognized through staining. Its name literally means "colored material."
Sodium and bromine would form an ionic bond. The one valence electron from sodium would be transferred to the bromine atom in order to obtain octet for both.
