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:
Gathering evidence.
Explanation:
Scientific evidence refers to the information obtained by research or observation.t This is the root of the scientific method because it's how an investigator evaluates different ideas, theories, or hypotheses. The mechanism of science involves explaining the phenomena we see in the world that match the data one has collected for the purpose. If one's theory doesn't match the evidence, then it needs to be revised. Therefore collecting evidence is a significant part of scientific investigation.
Answer:
Explanation:
In quantum mechanics and particle physics, spin is an intrinsic form of angular momentum carried by elementary particles, composite particles (hadrons), and atomic nuclei. Spin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum.
