The answer to the above question is:

94 degree Celsius for denaturation, 45-65 degree Celsius for primers anneal, and 72 degree Celsius for primer extension.

Denaturation: This process denatures the template (breaks the hydrogen bonds between the two strands) and activates the Taq DNA polymerase. You can adjust the activation period for a particular application or to increase yield, but it is typically kept around 94 degrees C for 2-3 minutes.

The primers anneal to the target sequence region of the template during this stage. The annealing temperature, which is typically 45–65 °C, depends on the Tm of the primers.

Primer extension/elongation: In this stage, Taq polymerase amplifies the target sequence at 72 degrees Celsius for the duration of the target's length, often between 45 and 3 minutes.

<h3>What is denaturation?</h3>

Denaturation is a biological process that alters a protein's molecular structure. As a result of denaturation, many of the weak connections or bonds (such as hydrogen bonds) that give proteins their highly organized structure in their native (natural) state are broken.

Radda [10]

Digestive juice is the name for all juices secreted by the organs from the digestive system such as salivary glands, stomach, pancreas and liver. All of them contain enzymes that are responsible for food (macromolecule) break down. Digestive juice from the stomach contains enzyme protease (pepsinogen) which breaks down proteins and stomach acids which is involved in chemical breakdown of food materials. So, that is why the wheat grains are broken into tiny particles.

Cyclic electron flow in the chloroplast produces
Aleonysh [2.5K]

Answer:

A. ATP

Explanation:

The Cyclic electron flow in the chloroplast includes only PSI and does not produce NADPH and oxygen gas. The process produces the only ATP.

During cyclic electron flow, electrons are transferred from the P700 reaction center to the ferredoxin and back to the PSI via cytochrome b6f and plastocyanin.

Since the electrons are not passed to the NADP+, NADPH is not produced. The proton gradient generated during this electron transfer drives ATP synthesis.
