BMC Genomics, 2021 Background Seisonidea (also Seisonacea or Seisonidae) is a group of small animals living on marine crustaceans (Nebalia spec.) with only four species described so far. Its monophyletic origin with mostly free-living wheel animals (Monogononta, Bdelloidea)

Microorganisms, 2021 It has been demonstrated that the englacial ecosystem in volcanic environments is inhabited by active bacteria. To know whether this result could be extrapolated to other Antarctic glaciers and to study the populations of microeukaryotes in addition to ...

Cancer Molecular Evolution [PDF]
Journal of Molecular Evolution, 2015 By far, the majority of studies in molecular evolution have focused on genetic change across one or more generations. Much less is known about the genetic changes that occur during the life time of an individual, or somatic evolution, of which cancer is probably the best-known example.

THE MOLECULAR EVOLUTION OF ACTIN [PDF]
Genetics, 1986 ABSTRACT We have investigated the molecular evolution of plant and nonplant actin genes comparing nucleotide and amino acid sequences of 20 actin genes. Nucleotide changes resulting in amino acid substitutions (replacement substitutions) ranged from 3-7% for all pairwise comparisons of animal actin genes with the following exceptions ...

Molecular Evolution in Collapsing Prestellar Cores [PDF]
, 2001 We have investigated the evolution and distribution of molecules in collapsing prestellar cores via numerical chemical models, adopting the Larson-Penston solution and its delayed analogues to study collapse.

Molecular Evolution of Aphthoviruses
Virus Genes, 1995 Aphthoviruses are an important group of animal pathogens. A combination of genetic and structural studies has revealed one of the main principles governing their evolution: severe limitations to variation imposed by functional and structural constraints, in conjunction with high mutation and recombination rates operating during genome replication ...

DNA Polymerases Engineered by Directed Evolution to Incorporate Nonstandard Nucleotides
Frontiers in Microbiology, 2014 DNA polymerases have evolved for billions of years to accept natural nucleoside triphosphate substrates with high fidelity and to exclude closely related structures, such as the analogous ribonucleoside triphosphates. However, polymerases that can accept

Elusive data underlying debate at the prokaryote-eukaryote divide
Biology Direct, 2018 Background The origin of eukaryotic cells was an important transition in evolution. The factors underlying the origin and evolutionary success of the eukaryote lineage are still discussed.

Genetic code evolution as an initial driving force for molecular evolution [PDF]
Physica A 388 (2009) 3809-3825, 2008 There is an intrinsic relationship between the molecular evolution in primordial period and the properties of genomes and proteomes of contemporary species. The genomic data may help us understand the driving force of evolution of life at molecular level.
