                         A genetic disorder is a disease caused in whole or in part by a change in the DNA sequence away from the normal sequence. Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or structure of entire chromosomes, the structures that carry genes). For example, Down Syndrome, Thalassemia, Cystic Fibrosis, Sickle Cell Anemia etc.

The most common patterns of transfer of genetic diseases are the following. Dominant genetic diseases are caused by a mutation in one copy of a gene. If a parent has a dominant genetic disease, then each of that person’s children has a 50% chance of inheriting the disease.

What is monoclonal antibodies?

Monoclonal antibodies are antibodies that are made by identical immune cells that are all clones of a unique parent cell. Monoclonal antibodies can have monovalent affinity, in that they bind to the same epitope (the part of an antigen that is recognized by the antibody).

What does the Journals of Biotechnology means?

Journals bascially publish scientific work. You can read papers of Bioetchnology online at any time. There are plenty of papers available online related to biotechnology and molecular biology.

Isolation of DNA means to take a DNA sequence and then use it for different purposes. For example transferring a part of DNA to another organism or other research purposes.

Dont be confused. In Dawn of Biotechnology topic, it has been explained that how Biotechnology became a revoloutinary field with the passage of time with new and discoveries being made time to time such as the discovery of Restriction enzymes, as well the fact that scientists started to know that which character is controlled by a particular gene or genes. All this is included in Dawn of Buoetchnology.

Plz explain the bone marrow and stem cells

Bone marrow is the spongy tissue inside some of your bones, such as thigh bones. It contains stem cells. The stem cells can develop into the red blood cells that carry oxygen through your body, the white blood cells that fight infections, and the platelets that help with blood clotting.
