A neurotransmitter may have an excitatory or an inhibitory effect on the postsynaptic cell, depending on __________.

Otrada [13]

A neurotransmitter can have an excitatory or inhibitory effect on the postsynaptic cell, depending on which of its receptor(s) are present on the postsynaptic (target) cell.

<h3>How do excitatory and inhibitory neurotransmitters act?</h3>

Sometimes neurotransmitters can bind to receptors and cause an electrical signal to be transmitted through the cell (excitatory). In other cases, the neurotransmitter can prevent the signal from continuing, preventing the message from being carried (inhibitory).

With this information, we can conclude that a neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse.

What effect would there be on the final daughter cell if the spindle fibers failed to pull a chromosome toward the pole, as in c

allochka39001 [22]

Aneuploidy can result in the final daughter cell if the spindle fibers fail to pull a chromosome toward the pole as in case of non-disjunction.

Explanation:

Aneuploidy is a condition which arises when one or more chromosome is missing in the final daughter cells.

Non-disjunction refers to the failure of chromosomal or chromatid segregation or separation during cell division. This results in erroneous meiosis or mitosis leading to the formation of final daughter cells or gametes with an extra or missing chromosome. This condition is aneuploidy.

Failure of separation or segregation of:

Homologous chromosomes occur in Anaphase I, affects four daughter cells.
Sister chromatids during Anaphase II, affects two daughter cells

This failure of separation leads to aneuploidy chromosomal abnormalities like monosomy, trisomy, etc which can cause diseases like Down’s syndrome, Turner’s syndrome etc.
