Answer:
d. Lysine is replaced by tryptophan (nonpolar)
Explanation:
Amino acid substitutions can have varying affects on the protein function, depending on the specific substitution and the location of the substitution.
If the substitution occurs in an important region, for example an enzyme active site, then the function of the protein could be destroyed.
Additionally, if the substitution replaces the amino acid with a highly different amino acid with different properties (eg. polarity), it could alter the structure and function of the protein.
Replacing lysine (polar) with a tryptophan (non-polar) changes the properties of the amino acid at that location, whereas the other substitutions do not.
Answer:
It looks to me that those are plant genes. And plant genes use the atmosphere and the hydrosphere to take in carbon dioxide. CO2 is in the atmosphere and once consumed, sugar ( Glucose ) is created. H2O is part of the hydrosphere and when water is consumed, Oxygen is the output. All of the spheres of the earth ( biosphere, hydrosphere, geosphere, and atmosphere ) are interconnected to create the things we know and see.
