Suppose that a single protein is significantly overexpressed in one of two different cell lines. The proteins are identical, but
mart [117]

Explanation:

Many mRNAs have sequences of 50 - 150 nt rich in A and U in the 3' untranslated region. These sequences, called AU-rich elements, are important to regulate mRNA stability, because they bind proteins that target the mRNA for degradation.

When a protein binds to the AU-rich element of the mRNA, the polyA tail can be shortened and/or the 5'cap is removed, promoting mRNA degradation. In addition, the AU-rich elements in some mRNAs have been shown to inhibit protein translation.

The mRNA of the overexpressing cell line is about 200nt shorter than the normal cell line; this could mean that it has a deletion in the 3'UTR comprising an AU-rich element. If this is missing, the mRNA will have an extended half-life (because it won't be targeted for degradation) or it will be translated more. As a result, the protein expression will be increased.

Analyze the oxygen levels of the victims. Were the levels higher or lower than normal? How can you reconcile this observation wi
fredd [130]

Answer:

In the case study of the Chicago cyanide murder, the oxygen levels were very low which lead to the death of the cells in the body (there would be signs of dead cells in the victims' bodies).

Explanation:

The mitochondrion is the powerhouse of all cells in the animal body, it is responsible for cellular respiration and production of adenosine triphosphate or ATP.

When the cyanide stops the activities of the mitochondrion, each cell in the body begins to die as a result of hypoxia, which is a condition where the body or a part of the body is deprived of oxygen.
