Within cultural heritage citizen science, the number of projects described becomes far fewer when measurement of data as opposed to collection or sorting of data is described, this is possibly because of the extra training or co-design needed to be more sophisticated above recognition, identification or transcription through "human computation" [16] which captures many of the extant activities.
The extant activities of the modern small ribosomal subunit, including its interaction with an RNA template (mRNA) and ability to assemble on it the complementary sequences of the tRNA anticodons, bear the features expected from the ancestral RNA replicase/RNA ligase.
Notably, the gharial lineage exhibits the highest extant activity of crocodilian CR1 retroposons with a total of approximately 2 Mb of virtually identical CR1-derived sequences in the gharial genome (supplementary fig. S4, Supplementary Material online).
In a high altitude region such as the Silvretta Alps (Switzerland/Austria), past and extant settlement activities are known to have had large influences on the alpine flora and vegetation.
About 40% of the extant enzymatic activities may be accessible by random cloning in E. coli, with a range of 7 73% between the five taxa examined.
For example, much of the extant hunter/gatherer activity data is based on observational or estimated activity levels and can be open to question.
Defining unambiguous biosignatures (isotope ratios of certain chemical elements, organic compounds or other phenomena strongly indicative of past or extant biological activity) is essential for the success of the two existing scientific enterprises, astrobiology and SETI, concerned with the search for extraterrestrial life within our Solar System and beyond.
The data obtained from ChEMBL may contain information related to all available biological activities extant for a given biological target (for example (K_{i}), ({K_{d}}), ({AC_{textit{50}}}), ({IC_{textit{50}}}), and ({EC_{textit{50}}})).
While both aspects constitute major challenges for the appropriation of returns to inventive activity, extant literature suggests that participation in the market for technology might actually resolve or at least alleviate these problems.
Subfamily II loci are more recent, exclusive to Felidae and show evidence for adaptation to extant RNA polymerase activity.
Our amniote-wide genome analyses suggest extant, "ongoing" CR1 activity in several lineages, as we detected the presence of more than 0.1 Mb of very young CR1 elements (i.e., no sequence divergence from the consensus) in the genomes of anole lizard, painted turtle, sea turtle, and four crocodilians, respectively.
