Answer: Polymerase chain reaction or (PCR) enables researchers to produce millions of copies of a specific DNA sequence in approximately two hours. This automated process bypasses the need to use bacteria for amplifying DNA.

Answer:

The methods by which DNA molecules multiply is known as REPLICATION

Explanation:

                             DNA REPLICATION.-

In all living organism DNA replication occurs. IN replication DNA replicates in this way making its replica or we can say its copy.

During replication, both the strands of DNA are separated first. Then each DNA strand function as the template and makes its own copy to make the full DNA molecule. This is the SEMICONSERVATIVE  mode of replication. In which each DNA molecule has one parent strand and one newly synthesized strand.

The replication start sight is ORIGIN OF REPLICTION( in E.coli ori c). At this location Helicase enzymes help in opening of the DNA.

The enzyme which has very unique function of adding nucleotide on the DNA strand and synthesizing DNA is DNApolymerase.

DNA replication occurs in 3' to 5' direction.

What initially causes a nerve impulse? release of enzymes out of the neuron movement of chemicals into the dendrites of the neur
sergeinik [125]

Answer:

movement of chemicals into the dendrites of the neuron

Explanation:

Nerve impulse occurs when electrical gradient is moved across the plasma membrane of a resting neuron this is done when the neuron receives a chemical signal from another cell or some other type of stimulus. This action potential then travels down the neuron’s axon as an electric current.

Resting potential occurs because of the difference in electrical charge across the plasma membrane of a neuron.

An electrical gradient is maintained by the sodium-potassium pump this is done across the plasma membrane of a neuron when it is not transmitting a nerve impulse this is the resting potential of the neuron.
