The vertebrate retina serves as an exemplary model for understanding evolutionary developmental biology. Here we present a comprehensive cross-species single-cell transcriptomic atlas of embryonic retinal development spanning six vertebrate species: human, macaque, mouse, chicken, zebrafish, and Xenopus.
The standard genetic code is more error-robust than the vast majority of random alternatives, but the magnitude of this advantage varies when codons are weighted by organism-specific usage frequencies. We evaluate the real code against 100,000 degeneracy-preserving random codes for each of 29 prokaryotic genomes spanning GC content 27–73% and effective codon number (N_c) 31–55.
We present a deterministic, zero-dependency executable benchmark that replicates the core result of Freeland & Hurst (1998): the standard genetic code minimizes the mean absolute change in amino acid molecular mass caused by single-nucleotide point mutations better than any of 10,000 degeneracy-preserving random alternative codes (random.seed=42).
