Imprinted gene example
For example, the gene encoding insulin-like growth factor 2 (IGF2/Igf2) is only expressed from the allele inherited from the father. Although imprinting accounts for a small proportion of mammalian genes they play an important role in embryogenesis particularly in the formation of visceral … Zobacz więcej Genomic imprinting is an epigenetic phenomenon that causes genes to be expressed or not, depending on whether they are inherited from the mother or the father. Genes can also be partially imprinted. … Zobacz więcej That imprinting might be a feature of mammalian development was suggested in breeding experiments in mice carrying reciprocal chromosomal translocations. Nucleus … Zobacz więcej Imprinting may cause problems in cloning, with clones having DNA that is not methylated in the correct positions. It is possible that this is due to a lack of time for reprogramming to be completely achieved. When a nucleus is added to an egg during Zobacz więcej In diploid organisms (like humans), the somatic cells possess two copies of the genome, one inherited from the father and one from the mother. Each autosomal gene is therefore represented by two copies, or alleles, with one copy inherited from each parent at Zobacz więcej Unfortunately, the relationship between the phenotype and genotype of imprinted genes is solely conceptual. The idea is frameworked … Zobacz więcej In insects, imprinting affects entire chromosomes. In some insects the entire paternal genome is silenced in male offspring, and … Zobacz więcej A similar imprinting phenomenon has also been described in flowering plants (angiosperms). During fertilization of the egg cell, a second, separate fertilization event gives … Zobacz więcej WitrynaFor example, along with Wilms' tumor, loss of imprinting of the IGF2 gene is associated with many other types of cancer, including lung, colon, and ovarian tumors …
