5. Often eukaryotic genes make more than one possible mRNA. There are actually two gene models for HBA1: one that is colored black and one that is colored blue. These are different isoforms of HBA1, which result from changes in the
way that the HBA1 gene is transcribed and how its introns are spliced. What differences do you notice between the
two isoforms of HBA1?

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.

Yes yes yes very good
