If it is known that there are 1870 adenyl nucleotides in a DNA molecule, 1130 guanyl nucleotides.

If it is known that there are 1870 adenyl nucleotides in a DNA molecule, 1130 guanyl nucleotides. How many nucleotides are there in DNA?

The DNA molecule contains A (adenine), which is always complementary to T (thymine) and G (guanine), which is complementary to C (cytosine). Consequently, if 1870 adenyl nucleotides, then 1870 thymine nucleotides.
1.1870 + 1870 = 3740 nucleotides A and T.
If 1130 guanyl, then 1130 cytosine.
2.1130 + 1130 = 2260 nucleotides G and C.
Now they need to be put together.
3. 3740 + 2260 = 6000 nucleotides in a DNA molecule.
