Answer:
as a dimer consisting of two identical monomers (80 kDa subunits) that are packed together via hydrophobic interactions
Explanation:
SDS-PAGE (sodium dodecyl sulphate–polyacrylamide gel electrophoresis), is an electrophoretic methodology used to separate proteins that have a molecular weight between 5 to 250 kDa. SDS is a well-known ionic detergent that is able to break hydrophobic interactions and hydrogen bonds. Moreover, size-exclusion chromatography is a filtration technique that separates molecules in solution according to their molecular size. In this case, SDS-PAGE showed that the target protein is composed of two identical subunits (monomers) of 80 kDa each, which were separated by the detergent and formed one single band in the SDS-PAGE gel.
The researchers will use mice instead of opossums or humans to determine whether the cells of the ear bones originated from the same embryonic cells as the cells that form the jaw in other vertebrates because in this type of experiment, organisms that are ideal are the ones that have a short life span, easy to be researched on and easy to mantain.
It will be very tedious and demanding to use opossums and humans in this type of practical experiment because,it is against the culture and norms guilding human living and existence to use humans as model organisms,opossums as well are very bad model organisms because unlike the mice,opossums are long lived and it will be very difficult to raise and maintain an opossum in a laboratory.
Humans and mice are both mammals just that human is a higher mammal but they share similar features in terms of pattern of development,though there is a clear difference during their early development,so because of the common ancestry shared by the mice and humans,the result of the experiment on the mice with share a close similarity with the pattern that is expected in humans.
Answer:
All
Explanation:
The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.
