If a strand of DNA has 48% cytosine what will the percent be for the other nitrogenous bases?

Answers

Answer:

There are 4 possible nucleotides that occur in two complementary sets. If 24% of the DNA is cytosin, the equal share has to be the complementary guanin. That makes 48% GC that leaves 52% AT, thus 26% are adenine and 26% thymine.

In comparison to the gelatin molecules in the candy, salt or sugar ions in water are significantly smaller. Water molecules go to a location with more solute to balance things out due to osmosis.
