Sentence examples for present day organisms from inspiring English sources

Such genes often have retained identical biological roles in present day organisms, indicated by a high degree of sequence homology.

Indeed, although the association between these two domains is specific of Thaumarchaeota and Viridiplantae, each domain is widely distributed in present day organisms, opening the possibility to reconstruct rooted phylogenies for each of them.

Because those retrotransposons that are unchecked by recognition of a repressor zinc-finger can go on to kill the host, we expect to observe in present day organisms a good correspondence between zinc-finger genes that recognize and bind to those retrotransposons that have recently entered the human lineage (and survived).

Due to its large distribution in present day organisms, DnaK was initially proposed as a good phylogenetic marker to infer ancient phylogenies and, more precisely, to decipher the relationships among the three domains of life and their main phyla [ 38- 40].

Our approach (see methods), similar to the approach introduced by Snel et al. [30], aims to predict the presence or absence of protein domains in ancestor organisms based on their distribution in present day organisms.

Phylogenetic study of protein sequences provides unique and valuable insights into the molecular and genetic basis of important medical and epidemiological problems as well as insights about the origins and development of physiological features in present day organisms.

The degree of divergence between the α chains reflects the degree of the evolutionary relationship between the organisms, because the hemoglobin chains have evolved independently of one another since the time of divergence of the lineages leading to the present-day organisms.

This facilitates research about present-day organisms.

You're probably well aware that all present-day organisms utilize deoxyribonucleic acid, or DNA, as the molecular basis for heredity.

By exploring NCBI databases, a researcher is, in effect, exploring evolutionary relationships among taxa, essential to drawing conclusions about present-day organisms.

You're probably well aware that all present-day organisms utilize deoxy ribonucleic acid, or DNA, as the molecular basis for heredity.
