A molecular biologist is engineering a synthetic plasmid for mammalian gene expression. Analysis of a specific double-stranded promoter region within this plasmid reveals that 31% of the nitrogenous bases are cytosine.
What is the percentage of each of the other three bases in this double-stranded promoter region?
31%31\%31% Adenine, 19%19\%19% Guanine, 19%19\%19% Thymine
19%19\%19% Adenine, 31%31\%31% Guanine, 19%19\%19% Thymine
19%19\%19% Adenine, 19%19\%19% Guanine, 31%31\%31% Thymine
38%38\%38% Adenine, 31%31\%31% Guanine, 38%38\%38% Thymine
