Answer:
A single nucleotide is made up of three components: a nitrogen-containing base, a five-carbon sugar, and a phosphate group. The nitrogenous base is either a purine or a pyrimidine. The five-carbon sugar is either a ribose (in RNA) or a deoxyribose (in DNA) molecule.
Explanation:
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.
