In northern Canada, a population of rabbits was predominantly white in color. The allele for white color is recessive (g), while the allele for gray color is dominant (G).
Over the last several decades, the average annual temperature of this area has
increased, and the long-term deposits of ice and snow have become scarce. We see
the result of this change in the graph above. Which of the following explanations for
the change in allele frequency shown in the graph best aligns with the theory of
natural selection?
No population can maintain equilibrium indefinitely
In a large population, mating is random, without mutations the allelic frequency
changes over time.
Random mating occurred among the rabbits and the allelic frequency was
altered.
Genetic variation existed. Natural selection occurred. Allelic frequencies
changed.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
