DNA is the molecule that is responsible for unity and diversity of life .
combination of DNA chromosomes genes
I assume you mean "unity in diversity"? All forms of life have common unifying features yet are amazingly diverse. Both of these facts are a result of our DNA . Similarities exists when common ancestors are recent, diversity occurs when genetics and environment interact and natural selection occurs. Adaptations are features that make an organism particularly well suited to its environment. Unity in the diversity - DNA is the common language of life. Humans have about 50% of the genes found in a banana; 99 % in a chimp. Evolution is "descent with modification", according to Darwin, accounting for Unity and Diversity.
It's not.
Yes, DNA does have a shelf life. It has a shelf life of about four years if it is properly preserved.

Simple. All of the millions of different life forms (the diversity of life) have come about by natural selection, whereby random mutations in the genes have either succeeded or failed. But all life can be traced back to a common single-celled origin. Thus we have the unity of life where we (possibly) share more than 50 % of our DNA with a crocodile.eg:analogous organs,homologous organs
phosphates and amino acids

All life has DNA.
Brand DNA is commonly defined as the clarity and unity within an organization about its greatest and farthest reaching purpose. For example: Starbuck's brand DNA is "Rewarding Everyday Moments" through an atmospheric experience.
The origin of life.
The unity and diversity of all life.
