This is based on the following three first principles: individual cell types are the basic components of neural circuit organization, the building blocks of circuit assembly, and the basic units of gene expression and regulation in the brain.
In general, biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the synthesis and creation of new species.
We speculated that hsp68 in these species arose by duplication of a basic unit of hsp70 genes typically arranged in Diptera species in inverted orientation.
The notion that there is an entity to be discovered that is the "basic unit of culture" as the gene is the basic unit of heredity will strike many as ludicrous.All the same, as the possibility of genetically engineering people gets nearer, natural selection may be, in his pithy phrase, "decommissioned".
The basic unit of this process is the gene,which is the focus of the forces of natural selection.
Second, nodes rather than genes form the basic unit of pathways, such that one node can be composed of several genes and one gene may reside in different nodes.
A gene is the basic unit of heredity.
"Such organisms need not maintain a full complement of genes," Dr. Lawrence wrote, referring to the basic unit of heredity.
Since a pathway represents as a network, the basic unit of the network (the node) is not always a single gene.
As Darwin would have loved to have known, genes made of DNA are the basic unit of inheritance.
