The two plates grab onto each other and lock in place is not a resulting situation of two plates colliding at a convergent boundary. When two plates colliding at a convergent boundary, what happenes is that one of the boundary either goes under or on top of the under, in order to release the energy that the two have stored because of the collision.
But this rule rule is applicable only for double stranded DNA molecule. The possibility of Adenine=40% and Thymine=60% is only in single stranded DNA molecule. In the question, the DNA sample referred is a single stranded DNA. hope it helps :D

Explanation:

Synapse plasticity
The ability of a given synapse to strengthen or weaken over time is known as synapse plasticity. The strengthening or weakening is in direct relation to the amount and way the synapse is used. The more frequently and vigorously a synapse is involved in activities, the more it will strengthen, just as in the case of muscles. This mechanism is important in learning and also lays the foundation of memory in the brain.
