Answer:
The correct answer will be option-DNA polymerase can only add nucleotides to the free 3' end
Explanation:
DNA replication process produces the exact copy of DNA which requires various enzymes. The function of adding a nucleotide to the daughter strand is performed by the enzyme called DNA polymerase.
The DNA polymerase enzyme catalyses the process of DNA replication which requires energy provided by the dNTP. The enzyme adds new nucleotides at 3'-OH end of the DNA which favour the reaction energetically.
Thus, the new DNA strand appears to be elongated in the 5' to 3' direction.
Answer:
scientist can learn how the rat has evolved based on where they live. it also helps find what the common ancestor was and all the common traits they have, for example rats in Norway may be used to the cold. and the rats in africa need to adapt to the heat and the constant threat of them being eaten.
The right answer is: <span>D. the formation of clouds
</span>Condensation is the second stage of the water cycle. The water vapor circulating in the atmosphere will encounter a colder air and it will turn into droplets, this phenomenon is called condensation.<span>
Water droplets accumulate in the form of clouds of different shapes, density, and altitude. This phenomenon is called condensation. Water vapor travels on the surface of the earth in the form of clouds.</span>
Xerostomia (hypo functioning of salivary glands )
Answer:
The answer is the first option.
Explanation:
Farming emerged because being a nomad was no longer suitable for increasing population size. Farming allowed people to stay in one place and properly feed their families, which was a definite positive impact on population size.
