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.
I think your question all turn into lowercases, uppercases, and lowercases are important in genetics because it can differentiate between the dominant and recessive forms.
let me explain at least how to calculate the offspring percentage:
for example, you have Rr crossed with another Rr (R for wrinkled peas and r for smooth peas), you just have to match between the four letters, and you will have four possibilities:
R and R
R and r
r and R
r and r
you will have RR, Rr, Rr, and rr
if we convert into percentages, it will give:
25% RR
50% Rr (there's two Rr so 25 + 25)
25% rr
