BIOINFORMATICS CROSSWORD 3

6. Sources of biological or chemical material that can be used as the starting blocks in laboratory experiments.
8. Tissue or organs from an individual of one species transplanted into or grafted onto an organism of another species, genus, or family. A common example is the use of pig heart valves in humans.
10. ______ of bioinformatics similarity search algorithms is defined as the significance threshold for reporting database sequence matches.
12. The science of the harmful effects of chemicals (including drugs) on living biological systems. It seeks to determine the mechanisms by which chemicals produce adverse effects in cells and organisms.
13. The group or recognizable pattern of symptoms or abnormalities that indicate a particular trait or disease.
14. User-selectable values, typically experimentally determined, that govern the boundaries of an algorithm or program.

1. Genes related by duplication within a genome. Evolve new functions, even if these are related to the original one.
2. The entire protein complement of a given organism.
3. An algorithmic procedure whereby an algorithm calls on itself to perform a calculation until the result exceeds a threshold, in which case the algorithm exits.
4. A foreign gene that is introduced into a cell or whole organism (e.g. transgenic mice) for therapeutic or experimental purposes.
5. Any agent that transfers material (typically DNA) from one host to another.
7. A DNA, RNA of protein sequence used to search a sequence database in order to identify close or remote family members (homologs) of known function, or sequences with similar active sites or regions (analogs), from whom the function of the query may be deduced.
9. A short stretch of amino acids each covalently coupled by a peptide (amide) bond.
11. A noncellular biological entity that can reproduce only within a host cell.
