phosophlipids containing a phosophate and 2 fatty acid chains connected by a glycerol molecule.
Explanation:
I think there is a 50% chance of the coin landing on either side because the labelling of the coin will not affect the balance of the coin, and therefore won’t alter the flip. Labelling the coin ‘b’ and B’ will result in a coin flip no different from if the coin remained unlabelled.
The major evolutionary episode corresponding most closely in time with the formation of Pangaea was the Permian Extinctions.
The Permian Extinctions happened around 300 million years ago and lasted for around 15 million years. It eliminated over 95 percent of water life and 70 percent of species on land. It was one of the largest extinctions in the history of Earth.
The gene p53, also called the guardian of the genome is located on the 17th chromosome in human genomes.
It was given this alternative name because it has a role in response to damage of DNA molecule and in preventing cancer.
The protein product of this gene stops the replication of damaged DNA, activates proteins that repair the DNA damage and if the reparation proteins fail to fix the damage it activates the process of apoptosis or so-called cell death in order to prevent the damaged cell to proliferate and potentially develop into a tumor.
