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%

its been noted for the past decade or so that there is some (approximately 5% to 7%) shrinkage in the brains of people who have schizophrenia, most notably in the gray matter, which is an important part structures in the brain’s amygdala, hippocampus and parahippocampus, which are all involved in memory storage and retrieval memory storage and retrieval.
