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.
Answer:
B
Explanation:
for someone to choke it means the person lacks oxygen in the sense that its oxygen path has been blocked so its B
The answer is E because all of the i I’ve is important to participate in conservation efforts
Answer: They lack nucleus and other organelles important for the synthesis of the enzyme.
Explanation:
The main function of the red blood cells is to supply oxygen throughout the body. The oxygen binds to the hemoglobin and travels throughout the body to ensure the supply of oxygen to various organs and more precisely the cells of the body.
The enzymes that is being synthesized inside the body is produced by the help of the gene and nucleus along with the other organelles involved in it.The mature red blood cells lack nucleus in order to increase the surface area for carrying the oxygen.
As there is no nucleus, mitochondria and golgi apparatus in the cell, there is no enzyme synthesis and broke down in the cell.
Yes, they do they only successfully reproduce in wet places, or after the rain.
