Dna replication a) is a slow process that results in virtually no errors. b) requires dna polymerase and rna polymerase. c) is a very fast process that results in numerous errors. d) requires the cooperation of over a dozen enzymes and other proteins.

B) requires DNA polymerase and RNA polymerase

Explanation:

DNA replication is mainly maid by the DNA polymerase and RNA polymerase enzymes, it needs others enzymes like helicase but are not a dozen of them.

DNA polymerase synthesize DNA in a main chain of DNA but needs a primer of RNA that is made by the RNA polymerase. With this process the DNA and RNA polymerase synthesize a new DNA chain that is bind to the main chain.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

nucleus

would be most reasonable answer tbh
