<span>After release into the synaptic cleft, neurotransmitters interact with receptor proteins on the membrane of the postsynaptic cell, causing ionic channels on the membrane to either open or close. When these channels open, depolarization occurs, resulting in the initiation of another action potential</span>

The postsynaptic cell becomes either more or less likely to fire an action potential.


If the postsynaptic cell is excited enough, it will continue passing the message to other cells.

Answer:

mRNA: 3' AUG-AAU-GCU-GCC-GGU-GA-5'

amino acids : methionine, asparagine, alanine, arginine, proline

type of mutation: deletion, missense

Explanation:

The mRNA sequence is complementary to the DNA sequence. A always pairs with T, C always pairs with G. Except this is an RNA sequence not a DNA sequence, so T is replaced with U.

The mRNA sequence is translated into an amino acid sequence based on the triplet code. The triplet code for this sequence is shown in the attached picture. Each triplet signifies a specific amino acid. The codon can be identified from the table and placed in sequence. We can see that the new DNA strand has caused a new amino acid sequence. It has also left us with an incomplete sequence, as GA cannot signify an amino acid.

The type of mutation is a single base deletion. We can see that the base C is missing from the 9th amino acid in the original strand. As you can see, this has an ongoing affect on all the bases in the rest of the sequence, as it changes the way the sequence is organised into codons. This results in a missense mutation.

There is a place in the lid where the fluid rushes to when you tip it, leaving the air bubbles in the cylinder of the bottle. In some companies it's a chemical inside the fluid that can evaporate over time and looses it's " magic" effect.
