Transcription and translation of a gene composed of 30 nucleotides would form a protein containing no more than amino acids.

will not form a protein of not more than 10 amino acids. during transcription the DNA carrying a certain information is converted to m-RNA which will then be converted to protein in a process referred to as translation. the reason why a gene with 30 nucleotide bases will not form a protein with more than 10 amino acids is every three nucleotide base code for one amino acid. so when you divide 30 by 3 the answer is 10. 

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.
