Answer:

A Ligase

B False

C To separate the double‑stranded DNA

Explanation:

The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories in order to make millions of copies of a specific sequence of DNA. PCR requires deoxynucleotide triphosphates (dNTPs) to synthesize new copies of the target DNA fragment, a thermostable DNA polymerase that adds nucleotides to new DNA strands, and primers that attach to complementary ends at each DNA strand. PCR has three phases: 1-Denaturation, where the double-stranded DNA molecule is heated to separate it into two single (separated) strands; 2-annealing, where the temperature is lowered in order to allow the primers to attach each DNA strand, and 3- extension, where the temperature is increased (again), and the thermostable DNA polymerase adds the appropriate dNTPs to new DNA strands. In consequence, annealing occurs at the lowest temperature. Moreover, during the denaturation stage, the temperature is increased at 90–95°C  in order to denature the DNA strands into single strands.

Scientists group materials together ________ it is easier to compare and study them that way
o-na [289]

The provided question is incomplete, the correct and complete question is as follows:

Choose the answer that best completes the sentence below.

Scientists group materials together ____________ it is easier to compare and study them that way.

A however

B but

C although

D because

Answer:

The correct answer is - option D because.

Explanation:

Researcher and scientists tries to group material together on their similarities and difference to one another which makes it easier to study and compare various type of materials.

It is the one of major reasons to differentiate materials between groups like liquids state, gases state,  plasma state and solid state materials. One can easily see the difference and comparison is very clear on this type of grouping of materials.

Thus, the correct answer is - option D.
