Although gene conversion homogenizes duplicated segments and limits our ability to date duplications precisely by using sequence divergence [ 87, 88], these results indicate that duplications have possibly occurred many times within the complex region during primate genome evolution.
With its great sheets of color and capacity for careful gradation, the Technicolor of the 1940s yielded a robust saturation and range of tones that, though frequently imitated, have never been precisely duplicated.
Biotechnology products are highly complex and, unlike traditional chemical drugs, they cannot be precisely duplicated by a second manufacturer.
The absorption route from the intestinal content through the epithelial cells and connective tissue into the capillaries inside the villi cannot be precisely duplicated in in vitro intestine-based systems, such as the brush-border membrane vesicles (part ), isolated enterocytes, everted rings of the entire intestine (section ), and the entire intestinal wall or mucosal sheets (section ).
But the ritual evolves in small ways, and no crime bill ever precisely duplicates the one before it.
He sent it back to the lab for stringent testing on monkeys that would precisely duplicate the human trial conditions.
The complexity of living organisms and internal biological phenomena is impossible to fully and precisely duplicate with individual-level specificity using a computer.
Examples are honorary authorship, which might be expected in some countries but against journal guidelines, or an engineer's impulse to precisely duplicate published text about methods, which can result in self-plagiarism.
The objective of the hindcast is not to precisely duplicate past conditions, but to represent short-term processes such as storm-induced wind, rain, and surge, along with long-term hydrological variations, that affect ecological processes and ecological response to changes in hydrology.
However, such in vitro studies are limited as they cannot precisely duplicate all the in vivo conditions.
