The effect of the neurotransmitters tends to be fast, as in a case of external stimuli, which leads to a quick reaction of the body, towards that stimulus.
The effect of a hormone, however, is long-lasting, where hormones actually are working on the metabolic or structural situations, which are going to have a long-lasting effect on the body.
Answer:
The 5' end has free phosphate group while the 3' end has free OH group.
Explanation:
Each DNA strand has two ends that differ from each other with respect to the functional group. The nucleotide present at the 5' end of a DNA strand has a free phosphate group. This phosphate group of other nucleotides of the DNA strand is bonded in phosphodiester bonds. Likewise, the 3' end of a DNA has a free OH group. This makes the two ends of a DNA strand quite different from each other. A DNA new nucleotide can be added to the 3' end due to the presence of a free OH group.

The correct answer is "<span>result in a shortened polypeptide chain".
This is a defect in the genetic code wherein the mRNA transcribed from the DNA has a premature stop codon. A stop codon is a codon (three nucleotides) which will signal the translation process to stop by a release factor. The stop codons for humans are UAA, UAG, and UGA. In the event where there is a mutation involving a premature stop codon in the mRNA, then the translation process will end prematurely making the elongating polypeptide chain to also release prematurely. This polypeptide chain is shortened as the elongation process is interrupted.</span>
Answer:
La communication entre deux neurones se fait par l'intermédiaire de substances chimiques appelées neurotransmetteurs libérés dans la fente synaptique. Ces substances diffèrent suivant les synapses. Elles sont produites par le neurone qui envoie le message et elles sont reconnues par le neurone qui le reçoit.
