الجينات الخلوية تكبح وتمنع أن تتطور من كائن إلي آخر

As they say in the real estate business, location is everything. It looks like the same working principle applies to genes and their control sequences in the genome during embryo development. And not just the gene’s simple location in a linear sense, but its three-dimensional spatial location. During the growth of an embryo, genes that direct the developmental processes are precisely switched on and off. This highly complex process contextually confers specific properties to different c
