INVERSE RELATIONSHIP. "DNA regions which code for proteins are decreasing with organismic complexity (in humans 1.5%) and former “junk DNA” plays increasing important roles in gene regulation." https://lnkd.in/euyhznh View in LinkedIn

"INCREASING COMPLEXITY and diversity are caused by genetic innovations, new combinatorial patterns of genetic content, non-coding regulatory networks and modifications of the genomic architecture. Interestingly, increasing eukaryotic complexity correlates with expansion of non-coding DNA." https://lnkd.in/eJG-UVH View in LinkedIn

SYMBIOTIC VIRAL VESTIGE. "It was assumed that this “junk DNA” is a kind of selfish genetic element, with an inherent tendency to replicate themselves, in contrast with its helpful and symbiotic functions within host genomes." https://lnkd.in/euyhznh View in LinkedIn

VITAL MINORITY. "The genetic code now also codes for proteins and the protein enzymes form the protein bodies, which we know as cells, cellular parts that organize metabolism, tissues, organs and organisms, all of which we term life from the most primitive last universal common ancestor to human beings. The percentage of coding for such proteins in the human 3 billion base pairs is only 1.5%, however." https://lnkd.in/eg6uePF View in LinkedIn

THE NON-1.5%. "All the other DNA contains non-coding RNAs (up to 45%) and non-coding areas with unknown functions (55%) which I suggest represent non-coding RNAs of regulatory functions. This means in all organisms we can find the genotype and the encoded phenotype. The genotype contains the whole blueprint for the phenotype." https://lnkd.in/eg6uePF View in LinkedIn

WORTH REPEATING. "Until recently, only the protein-coding regions of DNA was thought to be crucial to coding. While this may well be the case in the prokaryotes, in higher eukaryotes this region is marginal (3%), for 97% of the eukaryotic genome consists of non-coding DNA." https://lnkd.in/eDswHmC View in LinkedIn

BANDWAGGON SCIENCE. "Accordingly, research concentrated on the 3% that coded. Such one-sided approach, however, left many questions unanswered." https://lnkd.in/eDswHmC View in LinkedIn

Q: "Why are the protein-coding genes of humans and mice 99% identical?" https://lnkd.in/eDswHmC View in LinkedIn

Q: "What actually happens with the 97% RNA remnants during post-transcriptional processing?" https://lnkd.in/eDswHmC View in LinkedIn
