DNA polymerases add nucleotides to the 3′ end of a polynucleotide chain. ... To initiate this reaction, DNA polymerases require a primer with a free 3′-hydroxyl group already base-paired to the template. They cannot start from scratch by adding nucleotides to a free single-stranded DNA template.
How is DNA replicated? Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.

Explanation:
Oil sand is an unconventional source of oil. It requires specialized technology and great expertise to win oil from associated waste materials.
The reason why some companies bother about such oil source is explained below;
- Prevailing cost of oil in the world market makes it profitable to extract these oil from sands. A high cost of oil crude oil is a good cause to produce oil form oil sands.
- Development of new technology can catalyze interest in profitable exploration from unconventional sources.
- Economic policies can also favor the production of this source of oil.
- Demand for oil in the market can jack up production levels that can also be met by oil from oil sand.
