TdT

In cells so young and bright, There's a polymerase with all its might, TdT is its name, so grand, Adding nucleotides, hand in hand. In pre-B and pre-T cells it resides, And acute lymphoblastic cells it guides, With its magical touch, it does impart, Junctional diversity, a work of art. The DNTT gene, where it's found, In humans, its secrets are tightly bound, A member of the X family, it plays, With polymerase λ and μ, in amazing ways. TdT helps the immune system grow, By creating receptors, don't you know, More TCRs mean more resistance to fight, Infections won't stand a chance, day or night. Though it's been around for quite some time, TdT's mysteries are still sublime, In 2016-18, a new behavior was seen, Trans template-dependent, a discovery so keen. So let's celebrate TdT, our whimsical friend, For its role in diversity, we commend, In the world of DNA, it's quite unique, A polymerase with a touch so chic. Random page: Pc world
