Answer: Adenine
Explanation:
The structure of the DNA double helix is complex in nature. There are two strands of DNA that are wound around each other. The nitrogenous bases are bonded with hydrogen bonding and base complementarity. According to the Chargaff's rule of base complementarity adenine always pairs with the thymine and guanine with cytosine. These nitrogenous bases are paired on the basis of hydrogen bonding. Adenine bonded with thymine through two hydrogen bonds whereas the cytosine pairs with guanine via three hydrogen bonds. During DNA denaturation these hydrogen bonds are broken whereas during DNA replication these hydrogen bonds are formed between the nitrogenous bases.
Answer:
Hunting by the early humans is the appropriate answer.
Explanation:
A set of huge animals, which thrived on Earth at the time of the Pleistocene epoch is known as the Pleistocene megafauna. These species got extinct during the Quaternary event of extinction. There are four theories, which have been considered as the probable causes of the extinction of Pleistocene megafauna. These are change in climatic conditions, hunting by humans, impact from a comet or an asteroid, and spreading disease. However, the majority of the evidence indicates that humans were the prime cause for the extinction to take place.
