Image insertion genetics.png thumb 300px An illustration of an insertion at chromosome level In genetics , an insertion also called an insertion mutation is the addition of one or more nucleotide base pair s into a DNA sequence. This can often happen in Microsatellite genetics microsatellite regions due to the DNA polymerase slipping. Insertions can be anywhere in size from one base pair incorrectly inserted into a DNA sequence to a section of one chromosome inserted into another. On a chromosome level, an insertion refers to the insertion of a larger sequence into a chromosome. This can happen due to unequal Chromosomal crossover crossover during meiosis . N region addition is the addition of non coded nucleotides during genetic recombination recombination by terminal deoxynucleotidyl transferase . P nucleotide insertion is the insertion of palindromic sequence s encoded by the ends of the recombining gene segments.

Unreferenced stub auto yes date December 2009 In opposition to mutations , modifications are included in the band width of the genome of an individual creature. Modifications are dependent on the plentifulness of the substrate, light, warmths, stress, training, and so on. A modification is a change in the physical appearance of an organism phenotype caused by environmental factors. Modifications are not inheritable as they do not affect the genes. Occurrence Modifications often occur in domesticated animals Decrease of the brain weight by 20 to 30 percent, decline of the cerebral cleavage embryo cleavage especially in the projection areas of the sense organs , changes in the hormone status and in the behaviour. Modificability In heredity the genes of the parents are passed on to their offspring unchanged. That is why the organisms which carry the same genotype should be identical in every feature. However, this is not the case. Due to environmental conditions they can vary from each other up to a certain point. There are two types of modifications the continuous modification and the switching modification. To illustrate the modificability you can take a look at our cultivated plants. The harvest of those plants do not only depend on the quality of the seeds but also greatly on environmental factors like the condition of the soil, the nutrient content of the soil, the fertilization, the humidity and temperature as well as the interference of other plant s. Example Dandelion If you take a lowland dandelion and plant half of it in the lowland and the other half in the mountains the result will be a dandelion with big leaves in the lowland and one with small leaves in the mountains. The reason is that in the lowland the environmental conditions are different from those in the mountains. DEFAULTSORT Modifications Genetics Genetics stub Category Genetics ... more details

Ori is the DNA sequence that signals for the origin of replication, sometimes referred to simply as origin . In E. coli , ori is some 250 nucleotides in length for the chromosomal origin oriC . The plasmid ori sequences are similar to oriC . During Bacterial conjugation conjugation , the Rolling circle replication rolling circle mode of replication starts at the oriT T for transfer sequence of the FAT plasmid. Bacteria have a single origin for replication. Eukaryote s have multiple Replicon genetics replicon s, each with an ori . The replicons range from 40 kb yeast and Drosophila to 300 kb plants in length. Mitochondrial DNA in many organisms has two ori sequences. In humans, they are called oriH and oriL for the heavy and light strand of the DNA, each is the origin of replication for single stranded replication.

A transcriptional activator is a protein that increases transcription genetics gene transcription of a gene or set of genes. Most activators are DNA binding proteins . Most activators function by binding sequence specifically to a DNA site located in or near a promoter genetics promoter and making protein protein interactions with the general transcription machinery RNA polymerase and general transcription factor s , thereby facilitating the binding of the general transcription machinery to the promoter. The DNA site bound by the activator is referred to as an activator site. The part of the activator that makes protein protein interactions with the general transcription machinery is referred to as an activating region. The part of the general transcription machinery that makes protein protein interactions with the activator is referred to as an activation target. Example The catabolite activator protein CAP also known as cAMP receptor protein , CRP activates transcription at the lac operon lac operon of the bacterium Escherichia coli . ref cite journal author Busby S., Richard H.

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 .

Deletion is the loss of genetic material. Any number of nucleotide s can be deleted, from a single base to an entire piece of chromosome. ref name Lewis Lewis R. 2005. Human Genetics Concepts and Applications , 6th Ed. McGraw Hill, New York. ref Deletions can be caused by errors in chromosomal crossover during meiosis . This causes several serious genetic disease s. Deletion also causes frameshift . Causes Causes include the following Losses from Chromosomal translocation translocation Chromosomal crossover s within a chromosomal inversion Unequal crossing over Breaking without rejoining For synapsis to occur between a chromosome with a large intercalary deficiency and a normal complete homolog, the unpaired region of the normal homolog must loop out of the linear structure into a deletion or compensation loop . Types Types of deletion include the following Terminal Deletion a deletion that occurs towards the end of a chromosome. Intercalary Deletion Interstitial Deletion a deletion that occurs from the interior of a chromosome. Effects Small deletions are less likely to be fatal large deletions are usually fatal there are always variations based on which genes are lost. Some medium sized deletions lead to recognizable human disorders.

Types Different types of mosaicism exist, such as gonadal mosaicism restricted to the gamete s or tissue or somatic mosaicism. Somatic mosaicism Somatic mosaicism occurs when the somatic cells of the body are of more than one genotype. In the more common mosaics, different genotypes arise from a single fertilized egg cell, due to mitotic errors at first or later cleavages. Another form of somatic mosaicism is Chimera genetics chimerism , where two or more genotypes arise from the fusion of more than one fertilized zygote in the early stages of embryo embryonal development.
