<h2>Answer:</h2>

<em>Guanine</em>

When DNA is extracted from E. coli cells and analyzed for base composition, it is found that 42% of the bases are cytosine. That means that there is also 42% of guanine base.

<h3>Explanation:</h3>

According to chargaff's rule :

DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine.
