It Is this turgor pressure that holds the cell firm and provides the characteristics of of plant structures such as leaves. When a plant has been without water for a very long time the central vacuole lose water which results in the cells losing its shape, and the whole leaf wilts.
Tay-Sachs disease is caused by mutations in the HEXA gene and inheritance is autosomal recessive . The HEXA gene gives the body instructions to make part of the beta-hexosaminidase A enzyme, which is needed to break down a substance called GM2 ganglioside.
i hope this helped! please mark me as brainliest and 5 stars >:)
Areas near continents where freshwater rivers enter the ocean. The ocean IS salt water.
Answer:
In fact, the key difference between "template based" and "template free" structural prediction methods lies in the different conformational initialization methods. Template based prediction method obtains the initial conformation by searching and recognizing the known structure which has homology or structural similarity with the target protein as the template; template free prediction method usually constructs the initial conformation from the beginning with a small structure fragment.
At present, no matter which method is used, the known structural information in PDB database will be used to construct an initial conformation which is far better than random conformation, thus significantly reducing the pressure of conformation search, including reducing the amount of calculation and reducing the dependence on high-precision force field
