Transcriptome profiling is a powerful method for assessing the relative importance of gene products in any chosen cell, tissue, organism, or condition.
Molecules, cells, tissues, organs, organisms, populations and ecosystems reflect the hierarchical organization of life.
We argue that these post-transcriptional ribonomic systems provide an information management and distribution centre for evolutionary expansion of multicellularity in tissues, organs, organisms, and their communities.
This analogy can be easily extended to tissues, organs, organisms and colonies, in equal measure.
A gene (whether 1 or 10,000) can only play a causal role because "the environment" — cells, tissues, organisms — uses genes to create proteins and ranks (which are then used to create more cells, tissues, and organisms).
Two means of contending with this situation are employed, and, depending on how they regulate the salt concentrations of their tissues, organisms are classified as osmoregulators or osmoconformers.
When unknown tissues, organisms, or tumor cells appear in a body, the immune system tries to identify them and, if it succeeds, it attempts to eliminate them.
Genetic evidence demonstrates the importance of the components of the Mediator complex for normal development of multi-tissue organisms.
One definition is "material exploited in contact with living tissues, organisms, or microorganisms" [ 71].
Organelles, cells, tissues, organisms and other biological objects in the images are all considered identifiable components.
