Description Genetic engineering is the manipulation, modification, and artificial recombination of DNA or other nucleic acid molecules to modify an organism or a population of organisms. The term genetic engineering is generally used to refer to methods of recombinant DNA technology, which grew out of basic research in microbial genetics.…
Chromosome Inversion
What are chromosome inversions? Inversions are a diverse class of chromosomal mutation. Most are small (<1KB). Others, for example, the famous 3RP inversion of Drosophila melanogaster, are several megabases in size, including several percentages of the entire genome, and encompass hundreds or thousands of genes. Inversions fall into two classes:…
Gene Transcription
Introduction Transcription is the synthesis of RNA from DNA. Genetic information flows from DNA to protein, the substance that gives an organism its shape. This flow of information occurs through the sequential processes of transcription (DNA to RNA) and translation (RNA to protein). Transcription occurs when there is a need…
