3. a mental representation of something: she's got a good idea of the layout of the factory. 4. the characterization of something in general terms; concept: the idea of a square circle is self-contradictory. 5. an individual's conception of something: his idea of honesty is not the same as yours and mine. 6. the belief that something is the case: he has the idea that what he's doing is right. 7. a scheme, intention, plan, etc: here's my idea for the sales campaign. 8. a vague notion or indication; inkling: he had no idea of what life would be like in Africa.
Since DNA replication moves along the parent strand in the 5' to 3' direction, replication can occur very easily on the leading strand. As seen in, the nucleotides are added in the 5' to 3' direction. Triggered by RNA primase, which adds the first nucleotide to the nascent chain, the DNA polymerase simply sits near the replication fork, moving as the fork does, adding nucleotides one after the other, preserving the proper anti-parallel orientation.
DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication.Each side of the double helix runs in opposite (anti-parallel) directions. The beauty of this structure is that it can unzip down the middle and each side can serve as a pattern or template for the other side (called semi-conservative replication).egardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions.
