Encyclopedia > The Evolution of the Genome



The Evolution of the Genome is a book edited by Dr. T. Ryan Gregory of the University of Guelph, Ontario, Canada, covering a wide range of topics in the study of genome evolution. The book includes chapters by 16 authors and deals with topics including genome size, genomic parasites (transposable elements and B chromosomes), polyploidy, gene duplication, ancient genome duplication, comparative genomics, and macroevolution. It was released in December 2004 by Elsevier, ISBN 0123014638. Summary Dr. T. Ryan Gregory (b. ... Established in 1964, the University of Guelph is a medium-sized university located in Guelph, Ontario, Canada. ...

Bartleman Premier Dalton McGuinty (Liberal) Area 1,076,395 km² (4th)  - Land 917,741 km²  - Water 158,654 km² (14. ... In biology the genome of an organism is the whole hereditary information of an organism that is encoded in the DNA (or, for some viruses, RNA). ... Charles Darwin, father of the theory of evolution by natural selection. ... // Definition Genome size refers to the total amount of DNA contained within one copy of a genome. ... Selfish DNA is DNA which is prevalent in the genome, not because its phenotypic effect is beneficial, but because it has properties which cause the number of copies of it within the genome to increase with time. ... Transposons are sequences of DNA that can move around to different positions within the genome of a single cell, a process called Transposition. ... Definition B chromosomes are small supernumerary chromosomes found in many eukaryotic nuclei that are believed to be largely non-coding and probably parasitic on the host genome. ... Polyploid (in Greek: πολλαπλόν - multiple) cells or organisms contain more than two copies (ploidy) of their chromosomes. ... Schematic of a region of a chromosome before and after a duplication event Gene duplication occurs when an error in DNA replication leads to the duplication of a region of DNA containing a (generally functional) gene. ... Description Ancient genome duplications, also known as paleopolyploidy (cf. ... Comparative genomics is the study of relationships between the genomes of different species. ... Macroevolution is the concept that evolution of species and higher taxa is the result of large-scale changes in gene-frequencies over time. ...

  • The cover contains numerous images of animals, plants, and other organisms, most of which apparently have personal meaning for Dr. Gregory, including one image on the back cover that is reported to be a modified image of his own red blood cells.
  • The timeline of production discussed in the preface indicates that Dr. Gregory began work on this book while still a graduate student.
  • As described in the preface, the book was originally to be published by Academic Press, but part way through production the company was purchased by Elsevier. The former Academic Press editor in charge of the project and his replacement both left the company while the book was being produced.
