Explanation:
In the depolarization step of action potential where the membrane resting potential is reversed by the rush of sodium ions into a neuron.
A membrane potential shift from -70mV to +30mV for a limited period of time is known as an action potential.
The moving action potential has three stages:
1) The depolarization step, where sodium ions rush into a neuron and reverse the membrane resting potential; and
2) repolarization, which is a mechanism that restores the resting voltage of the membrane and the ionic concentration in the cell, is caused by the closure of the voltage-gated sodium channels and the opening of the potassium channels.
3) Hyperpolarization, when excessive potassium ion efflux occurs as a result of some open potassium channels increasing potassium permeability and causing a drop in the membrane potential.
4) The action potential, which is a transient reversal of membrane potential that travels through the axon, comprises three phases that are described above.

Ever cell has a gene code that's exactly the cell but some don't use that dba strand because specific parts need specific DNA
Answer:
Cells need to do between divisions to make sure that a full set of DNA gets passed on to each daughter cell - The DNA must be copied so there is a full set of DNA to pass on to each daughter cell.
Answer:
No, in molecular cloning cutting mistakes can lead to in correct ligation
C) No, because cutting mistakes could lead to incorrect cloning.
Explanation:
in molecular cloning, if you want to insert a specific gene of interest in to specific vector, the selection of enzyme and strategy before that is very important. The restriction enzyme should be selected which restrict at the desired location in the cloning sites. Any mistake in these selection or undesirable mutation mistakes can lead to in correct or unsuccessful cloning results.
