These laws describe the inheritance of traits linked to single genes on chromosomes in the nucleus.]]> 2018-12-10 12:09:34 UTC https://padlet.com/thatnintendoplayer/qd0h7yh7agxu/wish/312871920 thatnintendoplayer https://padlet.com/thatnintendoplayer/qd0h7yh7agxu/wish/312876581 For more than a century, plant geneticists have been studying maize as a model system to understand the rules governing the inheritance of traits, and a team of researchers recently unveiled a previously unknown mechanism that triggers gene silencing in corn. Gene silencing turns off genetic traits, an important consideration for plant breeders who depend on the faithful inheritance of traits from one generation to the next.]]> 2018-12-10 12:27:10 UTC https://padlet.com/thatnintendoplayer/qd0h7yh7agxu/wish/312876581 thatnintendoplayer https://padlet.com/thatnintendoplayer/qd0h7yh7agxu/wish/312878884 In plant cells, when and at what level a gene is expressed is under tight control between transcription activation and suppression, Chopra explained. Small RNAs -- molecules essential in regulation and expression of genes -- can mediate methylation of DNA strands and shut down transcription activity, therefore playing a role in silencing inherited genes or transgenes introduced to produce desirable crop traits.]]> 2018-12-10 12:35:26 UTC https://padlet.com/thatnintendoplayer/qd0h7yh7agxu/wish/312878884
