Allele M causes Marfan syndrome and M is dominant, so even if there's an M and an m, that individual would have Marfan syndrome. This means Braden could have Mm or MM.
Answer:
true
Explanation:
Different bacteria like to grow at different temperatures. Thus, a microbiologist will incubate a particular strain of bacteria at its optimal temperature so that he can study it when it is healthy. By changing the temperature, he can study the bacteria while they are stressed. Organisms that grow best at human body temperature, which is approximately 37 degrees Celsius (98.6 degrees Fahrenheit), are called mesophiles. Those that grow in hot temperatures between 40 to 70 degrees Celsius (104 to 158 degrees Fahrenheit) are called thermophiles. Those that grow at hot temperatures above 80 degrees Celsius are hyperthermophiles. Those that live in very cold conditions are called psychrophiles.
Answer:
They are present in all living organisms.
Explanation:
Cells are the basic structures of all living organisms.
Autosomal dominant inheritance: A person affected by an <span>autosomal dominant disorder</span><span> has a 50 percent chance of passing the mutated gene to each child. The chance that a child will not inherit the mutated gene is also 50 percent.</span>
Answer:
The correct option is C. receptor dimerizaton.
Explanation:
Growth Factors are protein substances found in our blood and play an important role in intercellular communication. These protein substances bind to receptors on the surface of the cell, with the main result of the activation of cell proliferation and / or differentiation. Many growth factors are very versatile, stimulating cell division in numerous different cell types, while others are specific to a particular cell type.
For the activation of a growth factor, dimerization or oligomerization of the receptor is necessary for kinase activity to occur, triggering intracellular signaling cascades. The dimerization can be between two identical receptors (homodimerization) or between different members of the same family (heterodimerization). The dimerization of the receptor, leads to the activation of its tyrosine kinase and the transphosphorylation of the tyrosine residues, releasing a signal transduction into the cell.
