What is the approximate percentage of guanine in the DNA genome of E. coli?
Nadya [2.5K]

Answer:

25%

Explanation:

<em>The approximate proportion of G + C content in the genome of E. coli has been reported to be 50%. According to Chargaff's rule, the amount of guanine in any DNA must be approximately equal to the amount of cytosine. </em>Hence,

if G + C = 50 and G = C,

then

G = C = 25

Therefore, the approximate percentage of guanine in the genome of <em>E. coli </em>would be 25.
