One of the most common spontaneous lesions that occurs in dna under physiological conditions is the hydrolysis of the amino group of cytosine, converting the cytosine to uracil. what would be the effect on dna structure of a uracil group replacing cytosine?

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

a) carbon, hydrogen

b) carbon, hydrogen, oxygen, nitrogen

c) carbon, hydrogen, oxygen, nitrogen, phosphorus
