The nucleus is removed from the egg and discarded. And a fungicide used on fruits led to sperm abnormalities in rats-abnormalities passed down at least four generations. A dangerous state of affairs. Comparisons with their closest free living cyanobacteria of the genus Synechococcus having a genome size 3 Mb, with genes revealed that chromatophores underwent a drastic genome shrinkage.
Even by the middle of the 19th century Disraeli was saying "the world is wearied of statesmen whom democracy has degraded into politicians". This means that in the resulting cells, one will have 24 chromosomes and the other will have 22 chromosomes.
Number of cell varies greatly among the organisms; a single cell in unicellular organism to infinite number of cells in multi cellular organisms.
This methylated the same gene, downregulated it, and turned the rats into anxious wallflowers. In the last few weeks alone I've seen very different epigenetic stories coming across the science wires.
