| Whereas telomeres protect terminal ends of linear chromosomes, telomerases identify natural chromosome ends being different from broken DNA. Although telomeres play a crucial role in the linear chromosome organisation of eukaryotic cells, their molecular syntax descended from an ancient retroviral competence. This is an indicator for the early retroviral colonization of large double stranded DNA viruses, which are putative ancestors of the eukaryotic nucleus.

This contribution will demonstrate an advantage of the biosemiotic approach towards our evolutionary understanding of telomeres: focus on the genetic/genomic structures as language-like text which follows combinatorial (syntactic), context-sensitive (pragmatic) and... |

| The development and growth of fungal organisms depend on successful communication processes (a) within the organism and between organisms, (b) with the same or related species and (c) with non-related organisms. In order to generate an appropriate response behaviour, fungal organisms must also be able to (d) correctly interpret meaningful information from the abiotic environment. However, these communication and interpretation processes can also fail. In such cases the overall results can induce disease-causing and even lethal consequences for the organism. 

	This review will not enrich the knowledge of specialists in fungal research, but will demonstrate to a broader readership the different levels of fungal... |

| Communicative competences enable bacteria to develop, organise and coordinate rich social life with a great variety of behavioral patterns even in which they organise themselves like multicellular organisms. They have existed for almost four billion years and still survive, being part of the most dramatic changes in evolutionary history such as DNA invention, cellular life, invention of nearly all protein types, partial constitution of eukaryotic cells, vertical colonisation of all eukaryotes, high adaptability through horizontal gene transfer and co-operative multispecies colonisation of all ecological niches. Recent research demonstrates that these bacterial competences derive from the aptitude of viruses for natural genome editing.... |

| Telomeres identify natural chromosome ends being different from broken DNA through differences in their "molecular syntax" (M.Eigen) which determines the functions of reverse transcriptase and its integrated RNA template, telomerase. Although telomeres play a crucial role in the linear chromosome organization of eukaryotic cells, their molecular syntax descended from an ancient retroviral competence. This is an indicator for the early retroviral colonization of large double stranded DNA viruses, which are putative ancestors of the eukaryotic nucleus.
