Dna

When science was in its foundational stage It was difficult to establish one’s parentage If a child was asked to give proof of its parents It would blink and wonder at the silly question. It was like questioning why the sky is blue The sky is blue because the grass is green It would say, so and so is surely my dad; dear For it trusts the words of his mother; beloved. But with science achieving massive strides Thanks to the great duo; Watson & Crick Ones’ pedigree can be certainly documented When, DNA strands mutually match, indeed.
