Why is the genetic makeup of the daughter cells formed in meiosis different from the parent cell?

These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.

These Double bonds will react with hydrogen to form single bonds causing them to be SATURATED, because when the second bond is broken, each half of the bond is then saturated with a hydrogen atom.

In terms of saturated fats acids composition by percentage according to ChartsBin statistics collector team 2011, Fat Composition in different Cooking Oils, ChartsBin.com, palm oil is 14.192, coconut oil is 91.92 canola is 7.46,palm oil 51.57, butter 65%-68%.Here you can see that the order of saturated fats from the highest gives- Coconut,butter, palm oil,olive oil and Canola as the last

Lana71 [14]

Answer:

The results of the experiment is a process called competitive inhibition.

Explanation:

Competitive inhibition is a process where an inhibitor (RGD tripeptides in this case) that resembles a normal substrate bind the active site of an enzyme and prevents the a real substrate from binding and a product from being formed (blocking enzymes active site).

When RDG tripeptides are added the cells would not adhere to the dish (competitive inhibition).
