Protein folding is the physical process by which a protein chain acquires its native 3-dimensional structure, a confirmation that is usually biologically functional, in an expeditious and reproducible manner. It is the physical process by which a polypeptide folds into its characteristic and functional three-dimensional structure from random coil. Each protein exists as an unfolded polypeptide or random coil when translated from a sequence of mRNA to a linear chain of amino acids. This polypeptide lacks any stable (long-lasting) three-dimensional structure (the left-hand side of the first figure). As the polypeptide chain is being synthesized by the ribosome, the linear chain begins to fold into its three-dimensional structure. Folding begins to occur even during translation of the polypeptide chain. Amino acids interact with each other to produce a well-defined three-dimensional structure, the folded protein (the right-hand side of the figure), known as the native state<span>.</span>
Answer:
Global warming is the unusually rapid increase in Earth's average surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels.
Caverns are formed due to <span>Carbonic Acid which is found in ground water and which also dissolves limestone.</span>
Answer:
The answer is The Prefrontal Cortex
Explanation:
The Prefrontal Cortex is a part of The Frontal Cortex at the front of the brain and accounts for more than 10% of our brains. It controlls key functions which involve making decisions and plans, setting long term goals and self control. To see the effects in an example, you can search for the case of Phineas Gage. I hope this answer was helpful.
