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.
Best Answer: All polymerases - eukaryotic and prokaryotic, for DNA and RNA - process the strand serving as a template in the 3'->5' direction. That is the correct direction since the strand it is synthesizing is anti-parallel (runs 5'->3'). And as we should expect from those two facts, all polymerases - eukaryotic and prokaryotic, for DNA and RNA - elongate a chain in the 5'->3' direction.
