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.

Angiosperms are more advanced than gymnosperms because gymnosperms lack which structure found in angiosperms?
vlada-n [284]

Gymnosperms lack fruits so angiosperms are more advanced than them.

Compared to gymnosperms, flowering plants may thrive in a wider range of settings. Compared to gymnosperms, flowering plants mature more quickly and generate more seeds. Additionally, angiosperms have more complex and specialized woody tissues. Gymnosperms lack flowers and fruits and have unenclosed or coverless seeds on the surface of scales or leaves, in contrast to angiosperms, generally known as flowering plants, which have seeds that are contained within an ovary (typically a fruit).

What are trade winds?
Sever21 [200]

Answer:

The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth's equatorial region (between 30°N and 30°S latitudes). ... The weaker the trade winds become, the more rainfall can be expected in the neighboring landmasses.

What is the most likely result of a cell with a mutation in the gene that codes for the enzyme primase?
Andreyy89

Answer:

The consequences will depend on the type of mutation. For example, if the mutation is synonymous it will not have negative effects on the cell function. On the other hand, if the mutation produces amino acid diversity it may cause loss of function

Explanation:

Primase is an RNA polymerase that adds RNA nucleotides to the complementary DNA strand in order to prepare it for the RNA polymerase III during transcription initiation
