|
It forms inside the lysosomes.
|
|
|
is made up of two lipid bilayer membranes which in eukaryotic cells
|
|
|
is a complex of DNA and proteins that forms chromosomes
|
|
|
is formed from the nucleus when the cell divides to form more nucleus.

Detailed explanation-1: -During the completion of mitosis (telophase), two new nuclei form around the separated sets of daughter chromosomes (see Figure 8.29).
Detailed explanation-2: -During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
Detailed explanation-3: -During the early stages, individual tubules of the endoplasmatic reticulum (ER; shown in green) bind directly to chromatin. Then, as mitosis proceeds, extra DNA binding proteins that reside in the ER progressively immobilize some of the tubules, flattening them out to create the nuclear membrane.
