Question

Explain why complementarity would have been necessary for the development of self-replicating molecules

Short answer

Complementarity helps the replicating pair to have correct sequence identity and orientation which helps the division of large biomolecules by assembling small units.

Step-by-step solution

Step 1. Complementarity

It refers to a lock and key system which is an important feature in DNA RNA translation and transcription. The strand which is to be synthesizedthe alignment of the nucleotide sequence is such that they are complementary to each other more like a mirror copy.

Step 2. Importance

More complex molecules formed as a result of complementarity which ismore aligned, organized,and hasa better adaptation. DNA has a property of self-replication as it replicates the copy formed should have the similar characters which can be achieved by preparing a complimentarycopy with the help of enzymes to store all genetic information without any error as it would result ingenetic deformity. Complementarity will help restore the original genetic information.
