Answer:
Denature DNA; anneal primers; extend primers.
Explanation:
PCR (polymerase chain reaction) amplifies a small amount of sample DNA into multiple copies. The reaction mixture mainly consists of Taq polymerase enzyme, primers, sample DNA to be amplified, and deoxyribonucleotides (dNTPs). The first step is the denaturation of the DNA molecule into single strands and is facilitated by heat. This is followed by primer annealing to the single-stranded DNA molecules. Primers attach to the primer-binding site on each DNA strand which in turn now serves as a template for DNA synthesis catalyzed by Taq DNA polymerase. Extension of primers by the addition of dNTPs produces new DNA molecules.

Answer:
Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.
Explanation:
DNA and RNA are the nucleic acids made of large number of repeating sub-units called nucleotides. Each nucleotide consists of a sugar, a phosphate and a nitrogenous base. There are four types of nitrogenous bases such as adenine (A), guanine (G), cytosine (C) and thymine (T) in DNA. Whereas, in RNA, base thymine is absent and it is replaced by uracil (U). Each base makes one nucleotide with sugar and phosphate.
While scanning the nucleotide one see a u nitrogen base, it means this nucleotide is a part of RNA because nitrogenous base uracil (u) is only present in RNA.
This question has little context, but I understand what you are trying to say.
The reason why dark moths survived while light moths weren't able to survive is due to the dark moths having conditions that allowed them to camouflage better than the light moths. An environmental condition that would allow this would be the dark moths and the light moths living in the same dark environment.
