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.

The most ethical decisions for usage of genomic data and technology, like sequencing human genomes for customized treatments and
Sati [7]

The most ethical decisions for usage of genomic data and technology, like sequencing human genomes for customized treatments and constructing deadly pathogens for study, are based on Consensus.

<h3>Waht is Consensus in a scientific community?</h3>

It normally implies settlement of the supermajority, aleven though now no longer always . Consensus is executed via scholarly communique at conferences, the book process, replication of reproducible consequences through others, scholarly debate, and peer review.

In short, a systematic consensus tells us matters that we've already learned, and it shall be realized whilst matters have stopped being debated withinside the sciences.Scientific consensus is the collective judgment, position, and opinion of the network of scientists in a selected discipline of study.
