Answer:
A fusion protein can be sythesized to carry a specific tag, which is useful in identifying the proteins in various experiments. Fusion proteins with the FLAG epitope bind to specific anti-FLAG antibodies and carry this extra sequence: Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys. The bioteh company that sells anti-FLAG antibodies states that fusion proteins carrying the Flag epitope display the sequence on the surface of the protein. This is likely <u>A short hydrophilic 8-amino acid peptide</u> because<u> of its hydrophilic nature</u> of the eight residues are <u>Likely to be located on the surface of the fusion protein</u>, making FLAG highly <u>Specific and easily accessible for cleavage by enterokinase </u> and likely to interact<u> with other epitope and domains</u> Al with water.
Explanation:
FLAG, a short hydrophilic peptide consisting of 8 amino acids have been widely used as a fusion tag for purification and detection of a wide variety of recombinant proteins. the 3× FLAG system is an improvement upon the original system by fusing 3 tandem FLAG epitopes (22amino acids). detection of fusion protein containing 3× FLAG is enhanced up to 200 times more than any other systems.
<span>Answer: E. The liver makes bile, which is needed to absorb lipid-soluble vitamins.
</span>
The liver makes bile that absorbs vitamin A, D, E, and K which is lipid-soluble. If the liver damaged and the bile production is reduced, the absorption of those vitamins will be reduced too. Vitamin K has a role in blood clotting, so the symptoms probably caused by vitamin K deficiency.
Answer:
In plants, the cell wall is full of small holes called plasmodesmata. If there were no cellular membrane all of the fluid in the cell (cytoplasm) would just leak out. The membrane also acts as a barrier to the outside world, controlling the influx of nutrients, hormones, chemicals and other substances the cell uses.
In animals, if there is no cell wall so the absence of a cellular membrane would make all animals a pile of goop on the ground.
Explanation: in other words its important because it protects it from harmful things
