The correct answer would be DNA Profiling. When Joe denied being the father of Lisa, Lisa's mom took Joe to the court to prove that he was Lisa's biological father. One way of proving that he's truly the biological father is by undergoing both DNA's into DNA profiling.
(A)Until the onset of PUBERTY,
Answer:
Biodiversity is very essential to the health of an ecosystem.
Explanation:
Biodiversity is essential to the health of an ecosystem because biodiversity provides functioning ecosystems that provides oxygen, clean air, clean water, pollination of plants, pest control, wastewater treatment and many ecosystem services. The change of temperature of the environment greatly affect the organisms because the organisms needs specific environment for growth and development. Habitat change, climate change, invasive species, overexploitation, and pollution are the factors that affect biodiversity. These factors causes increase or decrease in the biodiversity of the ecosystem.
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.
