It's the sodium ion.
When a neural impulse is fired in both neurons, it is always cause by an excited electron in one neuron moving to the other neuron to destabilize the balance of ions trying to keep them at equilibrium. This action either depolarizes or hyper-polarizes the membrane. If it does, then sodium ions--the key deficient ones--can flow into that region of low charge and maintain that state of low charge, keeping the cell membrane stable.
PCR technique is important in STR profiling in order to amplify and detect the number of Stars at a specific gene loci.
<h3>What is Short Tandem Repeat (STR) profiling?</h3>
Short Tandem Repeat profiling is a technique in molecular biology used to compare allele repeats known as STRs at specific loci in DNA between two or more samples.
The PCR (polymerase chain reaction) technique used in STR profiling involves making multiple copies is a particular segment of DNA in order to make enough quantities detectable in the analysis.
Therefore, PCR technique is important in STR profiling to detect the number of Stars at a specific gene loci.

It could trigger nuclear fussion
Answer:
The answer is the flexibility of DNA.
Explanation:
The flexibility os DNA is what allows transcription factors at distant binding sites to do their job. The DNA loops like cooked spaghetti to bring far-off binding sites and transcription factors close to general transcription factor or mediator proteins.
