  1. Bivalent (genetics)

    Unreferenced date January 2008 A bivalent , sometimes referred to as a tetrad , is a pair of associated homologous chromosome s held together by a complex after chromosome replication. During meiosis the Prophase I stage of Meiosis I , the process of synapsis occurs in which bivalents are formed. Each replicated chromosome is composed of two chromatid s. Bivalents are formed as two homologous chromosomes undergo recombination. Chromosome movement to accommodate recombination places homologous chromosomes close enough to each other for a protein complex synaptonemal complex , consisting of a protein ZIP1 ZYP1 depending on species , to hold them together. This protein s sequence is not well conserved, though its structure is very similar in all species globular domains on the N and C termini with a well defined core . In the atypical model species D. melanogaster and C. elegans recombination occurs secondarily to synapsis. Most species Human, Mouse, Arabidopsis, Maize, Yeast, Lily, and many others create bivalents as a result of DNA repair and recombination. Recombination produces chiasmata which hold chromosomes together after the synaptonemal complex dissolves.

  1. Bivalent chromatin

    No footnotes article date October 2010 Bivalent chromatin is chromatin that contains both activating and repressing epigenetic modifications in the same area. Activating chromatin modifications increase the accessibility of the chromatin to RNA polymerase , where repressing modifications decrease the accessibility to RNA polymerase. Usually, these do not both occur at the same location, as it seems they would have countering effects however in bivalent chromatin, they are both present. The repressing modifications usually take precedence, causing the gene to become inactivated. Once the repressing modifications are removed however, the activating modifications attract transcription genetics transcription machinery, and the gene becomes activated. Bivalent chromatin is hypothesized to serve a role in genetic imprinting genetics imprinting and in development. References NLM content Verify source what NLM content? URL?

  1. Chiasma (genetics)

    A chiasma plural chiasmata , in genetics , is thought to be the point where two homologous non sister chromatid s exchange genetic material during chromosomal crossover during meiosis sister chromatids also form chiasmata between each other, but because their genetic material is identical, it does not cause any change in the resulting daughter cells . The chiasmata become visible during the diplotene stage of prophase I of meiosis , but the actual crossing over of genetic material is thought to occur during the previous pachytene stage. When each bivalent tetrad , which is composed of two pairs of sister chromatids , begins to split, the only points of contact are at the chiasmata. chiasma frequency 2 x recombination frequency where recombination frequency is recombination frequency no. of recombinants total no. of progeny The phenomenon of genetic chiasmata chiasmatypie was discovered and described in 1909 by Frans Alfons Janssens , a Jesuit professor at the University of Leuven in Belgium . ref Elof Axel Carlson, Mendel s Legacy The Origin of Classical Genetics , CSHL Press, 2004, ISBN 0879696753, p.xvii ref ref http books.google.com books?id 5ULXJQR4aEUC&pg PA182&dq Frans Alfons Janssens&ei ANqjS zVLKrkygTU2sniCA&cd 1 v onepage&q Frans 20Alfons 20Janssens&f false In pursuit of the gene from Darwin to DNA By James Schwartz Harvard University Press 2008 , p. 182 ISBN 0674026705 Retrieved 19 March 2010. ref A bivalent refers to the two homologous chromosomes 4 chromatids .

    Bacterial genetics is the subfield of genetics devoted to the study of bacteria. Bacterial genetics are subtly different from eukaryotic genetics, however bacteria still serve as a good model for animal genetic studies. One of the major distinctions between bacterial and eukaryotic genetics stems from the bacteria s lack of membrane bound organelles this is true of all prokaryotes. While it is a fact that there are prokaryotic organelles, they are never bound by a lipid membrane, but by a shell of proteins , necessitating protein synthesis occur in the cytoplasm .

  1. Classical genetics

    Unreferenced stub auto yes date December 2009 Classical genetics consists of the technique and methodologies of genetics that predate the advent of molecular biology . A key discovery of classical genetics in eukaryote s was genetic linkage . The observation that some gene s do not segregate independently at meiosis broke the laws of Mendelian inheritance , and provided science with a way to map characteristics to a location on the chromosome s. Linkage maps are still used today, especially in breeding for plant improvement . After the discovery of the genetic code and such tools of Clone genetics cloning as restriction enzyme s, the avenues of investigation open to geneticists were greatly broadened. Some classical genetic ideas have been supplanted with the mechanistic understanding brought by molecular discoveries, but many remain intact and in use. Classical genetics is often contrasted with reverse genetics , and aspects of molecular biology are sometimes referred to as molecular genetics .

  1. Forward genetics

    Forward genetics is an approach that encompasses several means of identifying the gene or set of genes that are responsible for a particular phenotype within an organism. Initially, this entailed the generation of random mutations in an organism, often through radiation or insertional mutagenesis ex. Sleeping Beauty transposon system Sleeping Beauty , and then through a series of breeding of subsequent generations, isolating individuals with an aberrant phenotype. Today there are many different means of following the general path of altering the genotype to observe the phenotype, several of which within the genomic era can be useful in the study of functional genomics . Forward genetics can be thought of as a counter to reverse genetics , which seeks to alter genes in order to illuminate their multiple phenotypes. Classical forward genetics By the classical genetics approach, a researcher would then locate map the gene on its chromosome by crossbreeding with individuals that carry other unusual traits and collecting statistics on how frequently the two traits are inherited together. Classical geneticists would have used phenotypic traits to map the new mutant alleles. Eventually the hope is that such screens would reach a large enough scale that most or all newly generated mutations would represent a second hit of a locus, essentially saturating the genome with mutations. This type of saturation mutagenesis within classical experiments was used to define sets of genes that were a bare minimum for the appearance of specific phenotypes. ref Greg Gibson and Spencer V. Muse. 2009. A Primer of Genome Science, Third Edition .
