The genetic secret revealed: Humans evolved from two separate ancient species

  • No comments
New research at the University of Cambridge reveals that the modern human genome was created as a result of a merger between two ancient populations, which separated about 1.5 million years ago and reunited about 300 years ago.

The experimental system: two nostrils from which exit ultrasonic beams of excited helium atoms (in blue) and of argon atoms or hydrogen molecules (in red). The blue beam passes through a magnetic device (in yellow) which causes it to bend, and merges with the red beam - then the argon atoms or hydrogen molecules undergo ionization, and enter the detector. The picture above shows a cross-section of the magnetic device

The figure shows a DNA strand with nucleotide bases (A, T, G and C) moving down through a pore the width of a molecule known as a "nanopore". The symbol X marks the location of the missing base that could lead to a disease outbreak. Through the attachment of a ring chemical molecule containing a sodium ion to the damaged site, the movement of DNA through the nanopore can be slowed down so that the point of damage can be located.

In the figure: the control factors are divided hierarchically into three levels of activity. The factors of the highest level (above) affect the state of the genetic material, thus determining the basic identity of the cell. The factors of the second level (in the center) determine the expression levels of the genes and thus shape the properties of the cell. The factors of the third level (below) are more dynamic in nature, and activate genes in response to changing environmental conditions.

Weizmann Institute scientists have developed a method for deciphering the control code of the genome and through it have revealed new principles in regulating the expression of genes
