Download this file, its about stem cell technologies animation. Stem cells are biological cells found in all multicellular organisms, that can divide (through mitosis) and differentiate into diverse specialized cell types and can self-renew to produce more stem cells.

In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues. In a developing embryo, stem cells can differentiate into all the specialized cells (these are called pluripotent cells), but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues.

This is metabolism animation. Metabolism refers to all the physical and chemical processes in the body that convert or use energy, such as:

    * Breathing
    * Circulating blood
    * Controlling body temperature
    * Contracting muscles
    * Digesting food and nutrients
    * Eliminating waste through urine and feces
    * Functioning of the brain and nerves

This file is about DNA Cloning animation using flash media or swf format. DNA cloning is a technique to reproduce DNA fragments.  It can be achieved by two different approaches:  (1) cell based,  and (2) using polymerase chain reaction (PCR).  In the cell-based approach, a vector is required to carry the DNA fragment of interest into the host cell.  The following figure shows a typical procedure by using plasmids as the cloning vector.

If you wanna know about How to make recombinant DNA you can download this animation. Recombinant DNA (rDNA) is a form of artificial DNA that is created by combining two or more sequences that would not normally occur together.

In terms of genetic modification, it is created through the introduction of relevant DNA into an existing organismal DNA, such as the plasmids of bacteria, to code for or alter different traits for a specific purpose, such as antibiotic resistance.

This file is Gene Modification animation. You can learn more about efter download this file using flash media or swf format.

Genetic modification, is the direct human manipulation of an organism's genome using modern DNA technology. It involves the introduction of foreign DNA or synthetic genes into the organism of interest. The introduction of new DNA does not require the use of classical genetic methods, however traditional breeding methods are typically used for the propagation of recombinant organisms.

To make new organism or to make recombinant gene, some one need to extract or insert DNA. This file will show you about step of DNA inserting animation using swf format or flash media

DNA is extracted from human cells for a variety of reasons. With a pure sample of DNA you can test a newborn for a genetic disease, analyze forensic evidence, or study a gene involved in cancer. Try this virtual laboratory to perform a cheek swab and extract DNA from human cells.
DNA insert using plasmid, so what it plasmid?

Plasmids are similar to viruses, but lack a protein coat and cannot move from cell to cell in the same fashion as a virus.

Plasmid vectors are small circular molecules of double stranded DNA derived from natural plasmids that occur in bacterial cells. A piece of DNA can be inserted into a plasmid if both the circular plasmid and the source of DNA have recognition sites for the same restriction endonuclease.

The plasmid and the foreign DNA are cut by this restriction endonuclease (EcoRI in this example) producing intermediates with sticky and complementary ends. Those two intermediates recombine by base-pairing and are linked by the action of DNA ligase. A new plasmid containing the foreign DNA as an insert is obtained. A few mismatches occur, producing an undesirable recombinant.

The new plasmid can be introduced into bacterial cells that can produce many copies of the inserted DNA . This technique is called DNA cloning.
