The RNA world hypothesis proposes that a world filled with life based on ribonucleic acid (RNA) predates the current world of life based on deoxyribonucleic acid (DNA) and protein. RNA, which can both store information like DNA and act as an enzyme like proteins, may have supported cellular or pre-cellular life. Some hypotheses as to the origin of life present RNA-based catalysis and information storage as the first step in the evolution of cellular life.The RNA world is proposed to have evolved into the DNA and protein world of today. DNA, through its greater chemical stability, took over the role of data storage while protein, which is more flexible in catalysis through the great variety of amino acids, became the specialized catalytic molecules. The RNA world hypothesis suggests that RNA in modern cells, in particular rRNA (RNA in the ribosome which catalyzes protein production), is an evolutionary remnant of the RNA world.
옛날에 조아라(www.joara.com)에 유명한 SF소설로 ‘스키마’가 있었는데(아마 출판도 했음) 거기서 나온 그것이 여기에 바탕한 것이었나?
당시에 정말 흥미진진하게 읽었는데 ㅎㅎ
The Greatest Show on Earth 를 읽다가 RNA World Theory가 나와서 다시 생각났다.
