Is there anything that we can learn from studying protein, the protein side of this story in its own or are the proteins bacely determined by the dna. We use both information to accesse early life components. And what about the again, my ignorance showing. Am there's dna that codes for proteins, and there's non coding dena, right? Junk dna like is that also useful to you in these investigations?

In the question to understand the biology of life, we are (so far) limited to what happened here on Earth. That includes the diversity of biological organisms today, but also its entire past history. Using modern genomic techniques, we can extrapolate backward to reconstruct the genomes of primitive organisms, both to learn about life’s early stages and to guide our ideas about life elsewhere. I talk with astrobiologist Betül Kaçar about paleogenomics and our prospects for finding (or creating!) life in the universe.
