Scientists worked backwards by looking into the amino acid sequence to determine the DNA base. They started with the mRNA which transcribes the codon into respective amino acids. This human gene is found on top of chromosome 11 in human DNA.

Answer:
independent, dependent, control
Explanation:
The independent variable is the variable that you change. For example, if we were growing plants and wanted to see if more sun made them grow higher, you would change the amount of sun that each plant is exposed to.
The dependent variable is what you measure. This <em>depends</em> on the independent variable. So, in our plant experiment, the height of the plant is the dependent variable.
Control. The control is what stays the same. So in our plant experiment, the amount of water, type of plant, type of soil, and all of these things would stay the same to insure that the results are equal.
