1. A transgenic organism expresses 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 interest disabled.
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 restriction sites. 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.
C4H10 AND C2H5 have the same empirical formula
Answer:
Both plant and animal cells have a nucleus and chloroplast where protein synthesis takes place.
Answer:
Due to absorption of more water.
Explanation:
A Cotton shirt takes more time to dry as compared to a synthetic shirt due to absorption of more water by the cotton fiber as compare to other fiber. Cotton absorbs much more water than other synthetic fibers, and attached to the molecules of cotton for longer period of time which means cotton fibers take more time to dry as compared to synthetic fiber which absorb little amount of water and loosely attached to the molecules of fiber.
