21 hours ago · Barbara McClintock at the Carnegie Institution found that some genes were able to move around within the genome. These genes were called mobile elements or transposons.
2 days ago · This accords with Barbara McClintock’s earlier report that the chromatin ends are different from DSB in that HR was never observed (McClintock, 1941). Telomeric uncapping–induced recruitment of DSB repair proteins is also seen in human fibroblasts (d’Adda di Fagagna et al., 2003).

3 days ago · As first predicted by Barbara McClintock in maize , transposition can result in gene disruption, chromosomal rearrangements, and heterochromatin expansion . Therefore, silencing mechanisms have evolved to prevent TEs from mobilizing, including the RNA-directed DNA methylation (RdDM) pathway in plants ( 3 ).

These genes were called mobile elements or transposons On June 26, Nature published a paper by researchers at the University of California, Berkeley, and the Arc Institute in the U.S. describing a new RNA-guided gene editing ...
4 days ago · The discovery of transposons is credited to Barbara McClintock, who observed their behaviour in maize (corn) in the 1940s. Her work demonstrated that certain genetic elements could move around within the genome, causing changes in the colouration of maize kernels. Mechanism of Action of Bridge Recombinase Mechanism
1 day ago · Crossing Over. Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes — one from the mother and one from the father — line up, parts of the chromosome can be switched.
