An individual has two copies of a sickle-cell allele of hemoglobin in which a (historical) mutation replaced the underlined A (see above) with a T. Explain how this change in genotype causes a change in phenotype. For full credit, address (1) the sequence of the protein, (2) the three-dimensional structure of the protein, and (3) the consequences for the red blood cells and the individual.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.

what? are the statements?
