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.
The three parts of an amono acid are the carboxyl group(-COOH) an amino group(-NH2) and a radical that differs from amino acid to amino acid(-R)
Answer:
FALSE
Explanation:
But carbon-14 dating won't work on dinosaur bones. The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old. Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old. To determine the ages of these specimens, scientists need an isotope with a very long half-life. Some of the isotopes used for this purpose are uranium-238, uranium-235 and potassium-40, each of which has a half-life of more than a million years.
Mechanical waves cannot move without a medium
18. Enzymes bind with chemical reactants called substrates. In some reactions, a single-reactant substrate is broken down into multiple products.
20. stored evergy is released whenever these chemical bonds are broken in metabolic processes such as cellular respiration. Cellular respiration is the process by which the chemical energy of food molecules is released and partially captured in the form of ATP.
