Answer:
Enzymes like DNA polymerase III, HELICASE, Primase, Topoisomerase, ligase.
Explanation:
DNA replication is an important process that must occur prior to cell division. DNA content of a cell becomes duplicated in the process. This process, however, cannot occur without some vital elements that play specific roles. These elements are mostly enzymes which includes DNA polymerase III, HELICASE, Primase, Topoisomerase, ligase.
DNA POLYMERASE III is the main enzyme in this process, it adds nucleotides that are complementary to the unwinded DNA strand in order to synthesize its replica.
However, a new complementary DNA strand cannot be synthesized if the original double-stranded DNA does not unwind or separate. This process of unzipping the DNA into a Y-shaped replication fork is done by HELICASE.
DNA polymerase III starts adding nucleotides from the 3' end of the DNA strand. In order to recognize this end on the strand about to be synthesized, PRIMASE synthesizes a short strand of nucleic acid called Primer. This primer provides the DNA polymerase with something to start working on.
TOPOISOMERASE works on the double-stranded DNA prior to formation of replication fork by helicase. It helps prevent the DNA strands from becoming too tight and super coiled in order to make unzipping easy.
LIGASE helps to fill up those gaps in the DNA fragments during the synthesis of a complementary strand.
Answer:
Yes
Explanation:
Wetlands as salinity increases over time, wetlands become degraded, endangering wetland species and decreasing biodiversity
Answer:
Option A
Explanation:
Xylem is made of dead cells that transport water. Stomata are pores in leaves that help CO2 enter the plant. Chlorophyll absorbs sunlight (it cannot accept green light which is why leaves are green, cuz they reflect the green wavelenght)
Answer:
Explanation:
The animals are used for examining and determining the effect of a particular new drug for the treatment of the diseases and disorders before they are examined over humans. This practice is called as clinical trial.
The ethical issue associated with given type of testing is that animals have right to live and survive. They should not be subjected to the treatment where they experience harm or even death.
Anaerobic respiration is the process by which some organisms produce energy in the absence of oxygen. Instead of oxygen, organic and inorganic molecules are used as electron acceptors. One example of anaerobic respiration is fermentation.
In latic acid fermentation, one molecule of glucose undergoes glycolysis to produce two molecules of pyruvate. The two molecules of pyruvate then undergo fermentation to produce two molecules of lactate. The lactate will be transported to the liver. The lactate can be reconverted to pyruvate and utilized for energy. Latic acid fermentation occurs in the muscles.
