If a cell contains 38% guanine in its dna, how much cytosine does it have? how much adenine?

C and G are same and A and T are same. So If G has 38% then C is also 38%. I you add those together it makes 76%, then 100-76=24/2=12, so A and T are both 12%. If you add everything together it should equal 100%

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.
