Why are two different restriction enzymes used to cut the puc19 plasmid and the lux gene DNA? What would have happened if only t

snow_tiger [21]

This is because there might not be one restriction site bordering the gene to be cloned and the identical restriction site in the plasmid. Since these two restriction enzymes make compatible sticky ends, the insert has a chance of combining with the plasmid. To ensure efficient digestion, the two recognition sites should be more than 10 base pairs apart. If one of the enzymes is a poor cutter or if the sites are separated 10 base pairs or less, the digestions should be performed sequentially

Answer:

He meant that the supporting cells form a insulating coat on the nerve fibre called myelin seath. The myelin Sheath act similar to the rubber coating of household wiring because it electrically insulates the nerve fibre and speeds of conduction of nerve impulse..

Explanation:

The supporting cells of the nervous system are together called neuroglia or glial cells.
Unlike neurons these cells can divide in the mature nervous system and do not conduct nerve impulse.
Out of six types of glial cells, four are located in the central nervous system (CNS) and they are;astrocytes, oligodendrocytes, ependymal cells and microglia.
The remaining two types are the part of Peripheral nervous system (PNS) and include Schwann cells and Sattelite cells.
Among these , the oligodendrocytes of the CNS and Schwann cells of the PNS forms myelin sheath on the axons of the nerve cell that act similar to the rubber coating on the household wiring.
The myelin sheath electrically insulates the axon of a neuron and increase the speed of conduction of nerve impulse.
