Sign Up to like & getrecommendations! Published in 2023 at "ChemBioChem"
DOI: 10.1002/cbic.202300048
Abstract: Examination of the genetic code (GeCo) reveals that amino acids coded by (A/U) codons display a large functional spectrum and bind RNA whereas, except for Arg, those coded by (G/C) codons do not. From a… read more here.

DOI: 10.1007/s00709-017-1095-y
Abstract: The chloroplast and cytosol of plant cells harbor a number of parallel biochemical reactions germane to the Calvin cycle and glycolysis, respectively. These reactions are catalyzed by nuclear encoded, compartment-specific isoenzymes that differ in their… read more here.

DOI: 10.1016/j.isci.2021.102943
Abstract: Summary Ctenophores are a group of predatory macroinvertebrates whose controversial phylogenetic position has prompted several competing hypotheses regarding the evolution of animal organ systems. Although ctenophores date back at least to the Cambrian, they have… read more here.

DOI: 10.1017/s1473550418000423
Abstract: We propose that retinal-based phototrophy arose early in the evolution of life on Earth, profoundly impacting the development of photosynthesis and creating implications for the search for life beyond our planet. While the early evolutionary… read more here.

DOI: 10.1073/pnas.2116841119
Abstract: Significance It has been assumed that fungi are characterized by a haploid-dominant life cycle with a general absence of mitosis in the diploid stage (haplontic life cycles). However, this characterization is based largely on information… read more here.

DOI: 10.1073/pnas.2119217119
Abstract: Significance Owls, with their largely nocturnal habits, contrast strikingly with the vast majority of diurnal birds. A new spectacular late Miocene owl skeleton from China unexpectedly preserves the oldest evidence for daytime behavior in owls.… read more here.
