In a cell with defective chaperones, Question 14 options: proteins would not be able to exit the ribosome. the concentration of
misfolded proteins would be higher than normal. proteins would not be delivered to their appropriate cellular locations. ribosomes would not associate with the endoplasmic reticulum.
the concentration of misfolded proteins would be higher than normal.
Explanation:
Chaperones proteins are required for the correct protein folding of proteins. These proteins were first discovered in bacteria. The level of chaperones is increased under thermic stress conditions, it is for that reason that they are also known as heat shock proteins (Hsp). For example, Hsp70 is a chaperon protein constitutively expressed under stress conditions that is involved in the folding of protein precursors and the refolding of misfolded proteins. In humans, Hsp70 is encoded by the HSPA1A gene, and its increased expression level is related to different health problems including neurodegenerative diseases, cerebral ischemia and epilepsy.
Disposal of human waste through birds dropping the seeds of excreting them through the dropping of seeds from the plants which sometimes are carried by the wind
when trees are cut down, the bare surfaces left behind absorb more heat than the forest they replaced.And that heat helps draw air upward, pulling moist air in from nearby forested land that increases rainfall in the immediate area.
The cystic hygroma is a malformation in the neck or upper abdominal area and holoprosencephaly is a malformation or alteration in the facial area, not in the cranial area.
The only one where the shape of the skull is altered (mainly the area of the calotte) is the encephalocele.
Cell culture is a method that scientists use to grow a cell under a controlled condition or in a laboratory. To be able to do that, - The cell interest has to be dissected to an exposed of the same type.
