Organization of Genes. Genes are organized into units known as chromosomes. Humans have 23 pairs of chromosomes (46 in total). One chromosome in each pair comes from the person’s mother and the other from their father.

Plant peptide gamma-zein for delivery of biomolecules into plant cells

A method of introducing a molecule of interest into a plant cell having a cell wall includes interacting a gamma-zein peptide with a molecule of interest to form a gamma-zein linked structure. The gamma-zein linked structure is then placed in contact with the plant cell having a cell wall, and allowing uptake of the gamma-zein linked structure into the plant cell. Alternatively, a gene of interest can be expressed in a plant cell having an intact cell wall by interacting a gamma-zein peptide with the gene of interest to form a gamma-zein linked gene structure, allowing uptake of the gamma-zein linked gene structure into the plant cell, and expressing the gene of interest in the plant cell and its progeny.

Method of determining at least one variable of a WDM optical network

A method of optimizing a WDM optical ring network configuration using a genetic algorithm. Preferably, the method includes the steps of initially defining one or more parameters for a WDM optical network or portion of a WDM optical network and creating a plurality of parents each having a gene structure corresponding to the one or more parameters of the WDM optical network or portion thereof. The parents are then ranked according to predetermined fitness criteria. The highest ranking parents are then mated to form one or more children. Preferably, the children are then optionally mutated before or after testing to ensure that they satisfy predetermined network demands. Suitable children replace lower ranking parents to form new parents. The process is then repeated by mating the highest ranking parent in an effort to further optimize the network. Various steps in the genetic algorithm can be repeated until an optimal design is achieved.
