Hope this helped u!!
<span>Gram-negative bacteria have a cell wall that is <u>thin</u> and does not accept the stain, making it appear <u>red or pink</u><u />.
<u>
</u>Gram staining is used for differentiation gram-positive from gram-negative bacteria based on the characteristic of their cell wall. Gram-negative bacteria have a thinner cell wall than gram-positive bacteria. In this staining, bacteria are first stained with crystal violet dye. Only gram-positive bacteria will be violet colored because they can retain the dye thanks to their cell wall. The second staining with fuchsine or safranin will give the red or pink color to the gram-negative bacteria. <u>

Answer:
The correct answer is - Each cycle includes a "hot" denaturation phase (95C), which separates the hydrogen bonds that hold the strands of the template DNA together.
Explanation:
PCR is a polymerase chain reaction created by karry Mullis which is utilized to amplify a copy of DNA segments or a single copy of DNA or gene. The following are the steps involved in PCR reaction;
Denaturation: During this progression, the two-fold strand of DNA gets separated. The temperature required for this progression is 94 — 98 C.
Annealing: during this progression, Template DNA and DNA primers get attached. The temperature required for this progression is 55 — 70 C
Extension: During this progression, the polymerase includes the bases that are reciprocal to the template DNA strand. The temperature required for this progression is 65 — 72 C.
At such high temperatures, DNA polymerase gets denatured. As it very well may be found in the above strides for the isolation of the DNA strand high temperature of 94 — 98 C Is utilized. Taq polymerase can withstand such high temperatures.
