The given question is incomplete.The complete question is T/F When performing column chromatography to purify a protein of interest, one needs an assay to identify which fractions that contain the protein of interest. True or False: As discussed in lecture, we use a different assay for each different protein that we purify (For instance, the assay for protein A will be different than the assay for protein B which will be different than the assay for protein C, etc).

Answer: True

Explanation:

The sample contains different types of proteins in it and when the sample into chromatography column.

Different proteins have different affinity and based on the molecular size and weight they are separated.

So, according to the question if some one wants to assay protein A, it will be different for the protein B and different for the assay of protein C. This means that assays for different proteins will be different.

Hence, the given statement is True.

adoni [48]

1. The right answer is - Hypothalamus (manufactured by the hypothalamus, stored in the pituitary gland).

Vasopressin, or antidiuretic hormone, is a peptide hormone synthesized by the supraoptic and paraventricular nuclei of the hypothalamus, and released by the posterior pituitary gland (neurohypophysis).

It mainly has an anti-diuretic role in the kidney, where it causes a reabsorption of water via an action on the distal segment of the nephron during a dehydration body. Its gene is AVP located on human chromosome 20.


2. The right answer is - Increased Secretion of Vasopressin To Maintain Less Loss Of Water.

Vasopressin has an antidiuretic action: it decreases the volume of urine by increasing the water permeability of the collecting tube. It binds to the V2 receptor, which is coupled to a Gα protein, which activates a signaling cascade through the PKA. This causes the synthesis of aquaporin 2 (transmembrane pore) as well as its translocation to the apical / urinary membrane.
