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:
the predators and the prey that live there
Answer:
B
Explanation:
The lung not being not been able to exchange and remove the carbon dioxide created a health problem due to the concentration of hydrogen ions (H+) being 10X being higher than in normal body. Although the difference is just about 1, it will result increase hydrogen ion concentration 10 times, similarly an increase or decrease in pH from 4 to 2 will give rise to 100 times increase in hydrogen ion concentration. It can equally be applied to hydroxyl in concentration.
1 - A ground level plant develops curling tendrils that wrap around other objects so it can "climb".
This is a species changing over time as it was originally a ground level plant but began to climb higher.
2 - Over many generations.
This is because diversity takes time and has to be integrated through generations; for instance, marriage. In a family, it becomes more diverse after the next generation as each generation is likely to marry someone of another ethnicity and allow the family tree to become more diverse.
3 - Mutate or Survive
It depends on what it means by mutate - develop a mutation to make it adaptable? If that's the case, then mutations within the DNA would be a result of adaptation and increase survival. Otherwise, survive is the obvious answer as adaption allows for species to move around and live longer.
Hope this helps!
Answer: Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.
