By taking daily antibiotics, people are encouraging resistance by getting their immune systems used to the formulas. Antibiotic resistance<span> occurs when bacteria change in a way that reduces the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply, causing more harm. I think that people can help by not taking antibiotics for every little pain they have, instead try other simple remedies and only use medicines in cases where other remedies won't help. </span>

tructures used in recombinant DNA technology to carry the DNA from the cells of one species to the cells of another species are

Kobotan [32]

The process of fusing two or more DNA molecules to produce a hybrid is known as recombinant DNA. Restrictions endonucleases and ligases are two classes of enzymes that enable the technique.

When a restriction endonuclease detects a particular DNA sequence, it makes cuts inside or near that sequence. The recognition sequence of a restriction enzyme will haphazardly appear on every (1–4)n bases along a random DNA chain. The equation states how many fragments ends (measured in moles) are produced when a restriction enzyme cuts DNA.

Moles of DNA ends =2x(grams of DNA)/(number of bp)(660 g/mol / bp).

The equation describes how many ends are produced when circular DNA is digested by a restriction enzyme.

Mole ends=2x(moles DNA)x number of restriction sites.

The following equation can be used to determine how many ends are produced during the digestion of a linear molecule by a restriction endonuclease.

Mole ends=2x(molesDNA)number of restriction sites +[2x(moles of DNA)].
