As you read this many of the cells in your body are in a gradual process of division which results in the production of two daughter cells. In this process, known as mitosis, the cell duplicates its contents, including its DNA, before dividing. But the hardware is only part of a cell. Like a computer the cell contains programming information. For instance, tiny chemical signals—methyl groups—may be added to certain proteins or DNA sequences. You can read here about one way that this programming information is passed on to later generations. New research is now elucidating a different mechanism for preserving the cell's programming information.
Before the cell divides the DNA condenses and the various protein machines that normally bind to the DNA (to makes copies of the DNA genes, for instance) move away. The new research, however, found that one protein, known as MLL, remains connected to the condensed DNA. MLL connects to the DNA sequence adjacent to genes to influence the expression of the gene.
But during the process MLL moves to those genes that were most active. In this way MLL serves as programming information. MLL apparently identifies the genes that need to activate first in the new daughter cell. As the researchers wrote, "These findings implicate mitotic bookmarking as a component of ... gene regulation, which may facilitate inheritance of active gene expression states during cell division."
Indeed, it appears that MLL "bookmarks" active genes so they can quickly be identified in the daughter cell. It is another example of the additional layers of information in molecular biology, beyond the DNA itself.
It is also another example of the continuing failure of evolutionary theory where we must believe all this just happened to happen. MLL must have been created, or "recruited" as evolutionists prefer to imagine (who did the recruiting?). MLL must have luckily been coordinated with connecting and signaling molecules so as to attach to DNA. Even luckier, signaling molecules must have influenced MLL to switch to the active genes at just the right time. Then in the new, daughter, cell, the right molecules acted on the presence of MLL to activate those genes.
Impossible? Of course not. With enough multiverses anything can happen. A fact? Evolutionists think so. Religion drives science, and it matters.
