has disposition has disposition genomic material 1. Genomic material here is considered as a DNA or RNA molecule that is found in a cell or virus, and capable of being replicated and inherited by progeny cells or virus. As such, this nucleic acid is either chromosomal DNA, or some replicative epi-chromosomal plasmid or transposon. Genetic material is necessarily part of some 'material genome', and both are necessarily part of some cell or virion. So a genomic library is not considered a material genome/genetic material - rather, we could say that this genomic library is a 'genomic material sample' that bears the concretization of some genome. 2. Genomic material need not be inherited from an immediate ancestor cell or organism (e.g. a replicative plasmid or transposon acquired through some experimental modification), but such cases must be capable of being inherited by progeny cells or organisms. A nucleic acid macromolecule that is part of a cell or virion and has been inherited from an ancestor cell or virion, and/or is capable of being replicated and inherited through successive generations of progeny. 1. Note that at present, a material genome and genetic material are necessarily part of some cell or virion. So a genomic library is not considered a material genome/genomic material - rather, we could say that this genomic library is a 'genomic material sample' that bears the concretization of some genome. 2. A challenging edge case is experimentally delivered DNA into a terminally differentiated cell that will never divide. Such material does technically meet our definition - since we are careful to say that the material must be *capable of* being stably inherited through subsequent generations. Thus, we would say that *if* the cell were resume replication, the material would be heritable in this way. heritable genetic material exploratory term
