Thus at convergent boundaries, continental crust, made of granite, is created, and oceanic crust is destroyed. Two plates sliding past each other forms a transform plate boundary. ... In contrast to convergent and divergent boundaries, no magma is formed.
Answer:
It would most likely render the protein nonfunctional or mis-functional.
The mutation could result in three outcomes:
- Silent mutation, which changes the codon to the same amino acid. (AAA->AAG, both are lysine). But since the problem specified that it has a "slightly different amino acid sequence," we can assume this doesn't happen.
- Nonsense mutation, which changes a codon to a stop codon. This would end the chain of amino acids, making the protein potentially nonfunctional.
- Missense mutation, which changes a codon to another completely different codon. This can be harmful, as in sickle-cell disease, where just one amino acid, glutamic acid, is changed to valine.
Answer:
"It is the enzyme that breaks down acetylcholine in the synaptic cleft, ending stimulation of the muscle fiber. -It is the type of receptor found in the motor end plate that binds acetylcholine, initiating an electrical impulse."
Explanation:
Because an antibody is "made" relative to the antigen, but kept at low levels when you are exposed the first time ("primary immune response"). The second time you're exposed to the same antigen, memory cells recognize it and the body produces a high level of antibodies, and the level of antibodies usually remains higher for a longer time ("secondary immune response"). This is your basic immune response (primary and secondary).
This explains exactly why vaccines are effective to extremely effective.
