The nucleus has the function of controlling the inheritance, growth and development of cells, and is the carrier of genetic material and the control center of cells. Different cells survive for different times after losing their nucleus.

Cells in biology include five structures: cell wall, cell membrane, cytoplasm, organelles, and nucleus. Each structure has its own unique function, so what is the function of the nucleus?

Details

01

Eukaryotes generally die soon after they lose their nuclei, but red blood cells can live for up to 120 days without their nuclei; plant sieve tube cells can live for years without their nuclei.

02

A place where genetic material is stored and copied. It can be seen from the structure of the nucleus that the most important structure in the nucleus is chromatin, which is composed of protein molecu When the genetic material to transfer must be replicated in the nucleus.

03

Control centers for cytogenetics and cellular metabolic activity.Genetic material can be copied and passed on to offspring, and the genetic material must also represent the biological traits it controls, most of which are present in the nucleus.

04

The nucleus is also the control center for cell genetics and cell metabolism. For example, the British clone sheep “Dolly” is the nucleus of an ewe’s egg cell, which is then transplanted into the nucleus of another ewe’s breast cell and eventually developed from it.

05

Therefore, a more comprehensive description of the nuclear function should be that the nucleus is a genetic information database and a control center of cell metabolism and genetics.
