1. A transgenic organism expressese DNA that has been derived from another species. These organisms have altered genomes and are generated in the laboratory for the purposes of research, for example, the "knock-out" mice are tansgenic mice with a particular gene of <u>interest disabled</u>.
2. Recombinant DNA is the DNA that has been altered to contain genes, or portions of genes, from different organisms. The DNA molecules are formed in the lab using recombination methods to bring together genetic material from multiple sources and therefore creating sequences that are not found in the genome.
3. Restriction enzymes are found naturally in bacteria and they cut DNA at specific nucleotide sequences. These enzymes are also called restriction endonucleases, they cleave DNA into fragments at or near specific recognition sites called <em>restriction sites</em>. They are found in bacteria and archaea and they serve to provide a defense mechanism against invading viruses.
4. Biotechnology is the use or alteration of organisms, cells, or biological molecules to produce food, drugs, or other goods. Living systems and organisms are used to make or develop products. Biotechnology enhances cellular and biomolecular processes to develop technologies and product for the purposes of improving life and health.
5. Polymerase chain reaction is a technique that is used to quickly synthesize billions of copiies of a specific segment of DNA. It is a quick and a very efficient way to generate many copies of DNA. The process is applicable when there are small quantities of DNA to analyze. The events of PCR involves:
- separation of DNA strands,
- addition of primers,
- use of DNA polymerase to produce second strand of DNA.
6. In the process known as transformation, bacteria take up pieces of DNA from the surroundings. Bacterial transformation results from the uptake of naked DNA (DNA without associated cells or proteins). Transformation may also occur naturally in some species of bacteria.
Replica Plating refer to the process bacterial colonies are moved from a master plate to secondary plate.
<h3>What is Replica Plating?</h3>
Replica plating is method or tool use in microbiology in which one or more Petri plates that contain various solid selective growth media are inoculated with similar microorganisms colomies from a primary plate thereby reproducing the original pattern of colonies.
Therefore, Replica Plating refer to the process bacterial colonies are moved from a master plate to secondary plate.

Snow leopards are well adapted<span> to their high altitude homes where they may encounter deep snow and rocky terrain with little vegetation. Snow leopards have a well-developed chest that helps them draw oxygen from the thin air of the high mountains. Snow leopards also have short forelimbs with sizeable paws, long hind limbs, and a thick tail nearly a meter long. These adaptations help them balance on the rocky precipices of their home. Adaptations for cold include an enlarged nasal cavity that allows them to warm the cold air they are about to take into their lungs. Other adaptations for cold include long body hair with a dense, woolly underfur, and a thick tail that can be wrapped around the body. The snow leopards </span>pelage<span> enables them to blend into their surroundings. Their wide feet act like snow shoes.</span>
