an introduction
Cells are the basis for the formation of all living organisms. All organisms, whether plants, animals or microorganisms, are composed of cells. Even we humans are our bodies. Cells can be divided into plant cells that are involved in the formation of plants, animal cells that are the bodies of animals and the human body , And there is another division of cells, including what is the truth of the nucleus, including what is non-eukaryotic, and what concerns us here are the eukaryotic cells being the type that includes plant cells and animal cells.
Cell parts
Our bodies consist of millions of cells and these cells are animal and eukaryotic. These cells consist of many parts:
- Cell membrane: It is the thin membrane that envelops the cell.
- Cytoplasm: A fluid in which many of the organisms inside the cell swim.
- Nucleus: As we are talking about eukaryotic cells, they must contain a nucleus, the center of the cell. The nucleus contains the genetic material of the cell, so the nucleus is a center of activities, vital processes and information.
Therefore, the nucleus is the most important part of the cell as the center that contains the genetic material of the cell, each human genetic material is different from other people, and this article as the mark that distinguish each person from another, and contains the nucleus of long organ called chromosomes, which carry genes Genetics.
In many cases, genetic analyzes may be needed. These may include:
- In case of criminal suspicion.
- To determine the relationship of kinship, the parenthood of the child.
- This analysis is used when conducting a prenuptial examination, to ensure that the parties do not carry any of the genetic diseases.
What is genetic analysis
Genetic analysis or so-called genetic testing is an analysis of the genetic material in the cell to determine the genetic makeup of a particular person.
How to conduct this analysis
The samples are taken from cells containing nuclei. These samples are usually taken from white blood cells containing nuclei. They are confirmed to be free of diseases. An anticoagulant is added to them, then nutrients are added to the cells to stimulate splitting. Study them in a special way to reach their full analysis.
