Are there always gonna be an equal number of adenine and thymine nucleotides in a molecule

yes there will always be an equal number because they can only pair with eachother because of their chemical structures.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
