  2. 1. Wobble modifications and other features in transfer RNA important for decoding and reading frame maintenance

    Author : Joakim Näsvall; Glenn Björk; Michael O'Connor; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transfer RNA; Modified nucleosides; Decoding; Reading frame maintenance; Molecular biology; Molekylärbiologi;

    Abstract : Transfer RNA (tRNA) is the adaptor molecule responsible for bringing the correct amino acid to the ribosome during protein synthesis. tRNA contains a number of modified nucleosides, which are derivatives of the four normal nucleosides. READ MORE

  4. 2. Deciphering molecular mechanisms in the evolution of new functions

    Author : Hind Abdalaal; Joakim Näsvall; Paul Rainey; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Evolvability; functional trade-offs; collateral toxicity; duplication and amplification; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : The evolution of new genes and functions is considered to be a major contributor to biological diversity in organisms. Through de novo origination, “duplication and divergence”, and horizontal gene transfer, organisms can acquire new genetic material that can evolve to perform novel functions. READ MORE

  5. 3. Evolution of New Genes and Functions

    Author : Erik Lundin; Dan I Andersson; Joakim Näsvall; Diarmaid Hughes; Arjan de Visser; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : To answer major evolutionary questions, we need a better understanding of the effects of mutations on specific functions and organism fitness. The aim of this thesis was to elucidate how new functions evolve and potential trade-offs with the original function. READ MORE
