To investigate selection over longer evolutionary time scales in the coding sequence of age-1 and its neighbors, we contrasted patterns of polymorphism within species with sequence divergence between species using the McDonald-Kreitman test (McDonald and Kreitman 1991).
There is a rich sequence of Bronze Age, Iron Age, and Roman era occupation, as indicated by finds and features such as the Ringlemere gold cup and the Roman villas of the Darent valley.
Sequences of AGE-aptamer and control DNA aptamer (Control-aptamer) are below.
We examined adaptive evolution in the protein sequences of age-1 and its neighbors by contrasting polymorphism and divergence in their coding sequence using the McDonald-Kreitman test (McDonald and Kreitman 1991).
Somewhere in the middle of the climactic sequence of Avengers: Age of Ultron, Hawkeye (Jeremy Renner) remarks of the events on screen that "none of this makes sense".
The Madison Group which overlies the Bakken formation is a thick carbonate sequence of Mississippian age.
Vitrophyric varieties are surprisingly abundant for a volcanic sequence of this age, and are composed of predominant glass plus plagioclase (labradorite-andesine), pyroxenes (augite ± pigeonite and orthopyroxene), Ti-rich magnetite, and traces of apatite.
The sequence of physical aging and crosslinking, as well as reversal of the aging process was studied in order to separate the similar effects of aging and crosslinking.
He offers a sequence of five age-related stages through which a person must pass to reach moral maturity: (i) infancy (birth to age 2); (ii) the age of sensation (3 to 12); (iii) the age of ideas (13 to puberty); (iv) the age of sentiment (puberty to age 20); and (v) the age of marriage and social responsibility (age 21 on).
In this study, conducted in Eastern China, we used a sequential extraction method to analyze the changes in P species in sediments and soils in a coastal reclaimed area representing a sequence of soil ages.
Ancient evaporates occur widely in the Phanerozoic geologic record, particularly in those of Cambrian (from 570 to 505 million years ago), Permian (from 286 to 245 million years ago), and Triassic (from 245 to 208 million years ago) age, but are rare in sedimentary sequences of Precambrian age.
