Which of the following statements about Polymerase Chain Reactions is wrong?

Biology
1 answer:
KonstantinChe [14]3 years ago
5 0

Answer:

The correct answers will be option-B

Explanation:

The polymerase chain reaction is the technique which involves the chain of reaction. The reactions are performed which polymerises or make exact copies of the DNA in higher number from a small sample in vitro-conditions.

The PCR technique is based on the DNA replication mechanism which involves the DNA primers and Taq polymerase, a type of DNA polymerase enzyme.

The PCR proceeds in three steps that are denaturation, annealing, and extension in which the DNA is denatured to break the hydrogen bonds, the addition of the primers at both ends called reverse and forward primers which function simultaneously, synthesis of DNA and extension in which the sample is cooled.

Since the primers are added to both the strands and not on the same strands therefore, the selected option is the correct answer.

You will develop a brief portfolio detailing the history of tsunamis in a modern society that could be used to teach others.
Maru [420]

The 2004 Sumatra Earthquake and Indian Ocean Tsunami gave us a vivid description of menace of major tsunamis. It also suggested that tsunami science and engineering were inevitable to save human society, industries, and natural environment.

An answer can be found in Japan. Japan is the country the most frequently hit by tsunamis in the world. The experiences are well documented and are continued as the local legends. In 1896, the tsunami science started when the Meiji Great Sanriku Tsunami claimed 22,000 lives. An idea of comprehensive countermeasures was officially introduced after the 1933 Showa Great Sanriku Tsunami. The major works taken after this tsunami, however, were the relocation of dwelling houses to high ground and tsunami forecasting that started in 1941. The 1960 Chilean Tsunami opened the way to the tsunami engineering by elaborating coastal structures for tsunami defense. The 1983 Japan Sea Earthquake Tsunami that occurred during a fine daytime cleared the veil of actual tsunamis. The 1993 Hokkaido Nansei-Oki Earthquake Tsunami led to the practical comprehensive tsunami disaster prevention used at present, in which three components, defense structures, tsunami-resistant town development and evacuation based on warning are combined.

The present paper briefs the history of tsunami research in Japan that supports countermeasures.
