Tiny molecular machines that keep chromosome numbers correct have been identified

From ScienceDaily:“During cell division, a mother cell divides into two daughter cells, and during this process the DNA in the mother cell, wrapped up in the form of chromosomes, is divided into two equal sets. To achieve this, rope-like structures called microtubules capture the chromosomes at a special site called the kinetochore, and pull the DNA apart,” said Dr Viji Draviam, senior lecturer in structural cell and molecular biology from QMUL’s School of Biological and Chemical Sciences.
“We have identified two proteins — tiny molecular machines — that enable the correct attachment between the chromosomes and microtubules. When these proteins don’t function properly, the cells can lose or gain a chromosome. This finding gives us a glimpse of an important step in the process of cell division.”

As the unlikelihood of a random origin of the cell becomes more and more obvious, expect still more spates of journal articles from tone deaf profs on how to Fix anyone who doubts the randomness dogma.
