If a substitution changes the amino acid to a “stop,” it's called a NONSENSE mutation. frameshift, missense, silent or nonsense (hint: deletion or insertion will always be frameshift). Sickel cell anemia is the result of a type of mutation in the gene that codes for part of the hemoglobin molecule.
The type of protein that plays an important role in transmitting signals in the nervous system is : A. Ion channel membrane proteins
The opening and closing of ion channel membrane proteins leads to changes in membrane potential which conducts information over an axon or synapses
hope this helps

Warm produced from the radioactive rot of components somewhere down on the inside of the Earth makes magma in the aesthenosphere.</span>
