Exploring Genome’s Junkyard: In the Labyrinth of Evolution

Exploring Genome’s Junkyard: In the Labyrinth of Evolution narrates the progress of biological evolution, beginning with the conceptual introspection of gene and continuing with the contemporary understanding of the structural and function aspects of the human genome. Recent advances in human genome research have led scientists to the term biological dark matter, which refers to genetic material whose functionalities are not yet properly understood. Such dark matter has been recognized as non-coding, or junk DNA, and non-coding RNA, which was thought to be devoid of protein encrypting potential but contained 98-99% of the human genome. The mysteries of missing genes from its Dark DNA region are a hotbed of recurrent mutations. Hence, the presence of missing genes in evolutionary sibling species has indicated that the missing genes are not really missing but rather hidden in the mutational hotbeds of Dark DNA where they have steered the continuation of life’s evolutionary journey.
