Which of the atoms in guanine carry a partial negative charge (δ-) and which carry a partial positive charge (δ+?

There are two types of nitrogenous bases that form the DNA/RNA. These include the purines and pyrimidines.

Guanine is a derivative of purine and is made up of a fused pyrimidine-imidazole ring system with double bonds in conjugation. The molecular formula is C5H5N5O. Here, O being more electronegative than N will carry a partial negative charge while N will carry a partial positive charge.

the answer is alpha particles hope i you

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
