ABSTRACT To take complete advantage of the large and rapidly increasing body of sequence information, advanced technologies are very much required. Among the most powerful tools for genomics are high-density arrays of oligonucleotides or cDNAs. Exploration of the genome using DNA microarray should narrow the gap in our knowledge between gene function and molecular biology. Nucleic acid arrays or simply...

For those that watch television crime dramas, the use of DNA evidence appears to be the final nail in the conviction coffin. Television portrays DNA as direct evidence; evidence that proves the existence of the fact without the use of interferences or presumptions. In reality, DNA is wholly circumstantial in nature. In this paper I will be focusing on what...

Over the course of 350 million years, plants and insects have coevolved to counter each other’s defensive strategies. A variety of physical and biochemical mechanisms are used almost intuitively to help plants deter herbivorous pests. Chemical signals and compounds emitted by plants can be exploited by herbivores, predators and parasitoids to locate resources. In this review, we will look at...

The study of language has a unique history as modern linguistics began to develop in the 18th century, with work focused on reconstructing Indo-European studies. Current linguistics still practice reconstruction. However, further development has been issued on understanding why languages exist, and whether or not a certain form of speech is considered to be a dialect or a creole. Studies...
