DNA replication is Group of answer choices conservative. a one-step process. semi-conservative. not carried out by enzymes. not
Alex787 [66]

Answer:

The correct answer is: semi-conservative.

Explanation:

DNA replication is an important process in which the DNA is duplicated before cell division so each daughter cell can have a copy of genetic material.

DNA replication is <u>semi-conservative because one strand of DNA is new and the other one is the old strand</u>. To replicate itself, the DNA double helix is opened, and then each strand serves as a model for the new strands.

DNA replication is <u>not a one-step process</u>, as it takes several complicated steps in which <u>lots on enzymes participate</u> (like DNA polymerase and DNA helicase).

DNA replication is <u>also carried by prokaryotic cells</u>, though it's a much simpler process.

Excitatory neurotransmitters influence the receiving neuron to _____, whereas inhibitory neurotransmitters influence the receivi
Viktor [21]

Excitatory neurotransmitters cause the neuron to fire, and Inhibitory neurotransmitters cause the neuron not to fire.

Impulses are the signals passed from one neuron to another on the action of a stimulus. The impulses passed can be electrical or chemical. Neurotransmitters are the chemical molecules that help in the transfer of impulses between two neurons.

Chemicals like epinephrine, norepinephrine, and glutamate when released from the synaptic cleft of one neuron activate the receptors of other neurons, thereby initiating the other neuron to fire. These chemicals are called excitatory neurotransmitters.

Chemicals like GABA and glycine, when released from the synaptic cleft of one neuron do not activate the receptors of other neurons and hence the neurons will not fire the impulse. These chemicals are called inhibitory neurotransmitters.
