Selective pressures on genomes in molecular evolution [PDF]

, 2003
We describe the evolution of macromolecules as an information transmission process and apply tools from Shannon information theory to it. This allows us to isolate three independent, competing selective pressures that we term compression, transmission ...

A sea slug’s guide to plastid symbiosis

Acta Societatis Botanicorum Poloniae, 2014
Some 140 years ago sea slugs that contained chlorophyll-pigmented granules similar to those of plants were described. While we now understand that these “green granules” are plastids the slugs sequester from siphonaceous algae upon which they feed ...

Revision of Gyrodactylus salaris phylogeny inspired by new evidence for Eemian crossing between lineages living on grayling in Baltic and White sea basins [PDF]

PeerJ, 2018
In this research, grayling-specific Gyrodactylus salaris Malmberg, 1957 isolates from Baltic Sea basin were collected in Sweden for the first time. Samples were obtained in three drainage systems: Kalixälven (River Kaitum), Ljungan (River Sölvbacka ...

Evolution of giant molecular clouds across cosmic time [PDF]

, 2020
Giant molecular clouds (GMCs) are well studied in the local Universe, however, exactly how their properties vary during galaxy evolution is poorly understood due to challenging resolution requirements, both observational and computational. We present the

A Hierarchical Approach to Protein Molecular Evolution [PDF]

, 1999
Biological diversity has evolved despite the essentially infinite complexity of protein sequence space. We present a hierarchical approach to the efficient searching of this space and quantify the evolutionary potential of our approach with Monte Carlo ...

Molecular Phylogenetics and Mitochondrial Evolution [PDF]

Life, 2021
The myth of a “typical” mitochondrial genome (mtDNA) is a rock-hard belief in the field of genetics, at least for the animal kingdom [...]

Autonomous assembly of synthetic oligonucleotides built from an expanded DNA alphabet. Total synthesis of a gene encoding kanamycin resistance

Beilstein Journal of Organic Chemistry, 2014
Background: Many synthetic biologists seek to increase the degree of autonomy in the assembly of long DNA (L-DNA) constructs from short synthetic DNA fragments, which are today quite inexpensive because of automated solid-phase synthesis.

Optimal evolutionary control for artificial selection on molecular phenotypes [PDF]

Phys. Rev. X 11, 011044 (2021), 2019
Controlling an evolving population is an important task in modern molecular genetics, including directed evolution for improving the activity of molecules and enzymes, in breeding experiments in animals and in plants, and in devising public health strategies to suppress evolving pathogens.

Rate variation during molecular evolution: creationism and the cytochrome c molecular clock [PDF]

, 2017
Molecular clocks based upon amino acid sequences in proteins have played a major role in the clarification of evolutionary phylogenies. Creationist criticisms of these methods sometimes rely upon data that might initially seem to be paradoxical.
