Study: Enzymes act very specifically to control double-strand breaks

At ScienceDaily: "It's like an engine mechanic who has a set of tools at his disposal," Dr. Sung said. "The tool he uses depends on the issue that needs to be repaired. In like fashion, each DNA repair tool in our cells is designed to repair a distinctive type of break in our DNA." Read More ›

The larger lesson from the story of the Man With Two Fingerprints

Remember when DNA was Certain? When people were executed or spent life in prison on account of DNA evidence? “Your DNA is on it” was like Holy Writ. DNA was the guarantor of the Darwinian selfish gene. And now… The worst thing that ever happened to Darwinism was DNA mapping. Read More ›

Bacteria harpoon DNA from their environment, to fight antibiotics

Wait. What does this story remind us of? Oh yes, recently a writer at The Atlantic went so far as to express doubt about the claim of a Darwin-in-the-schools lobbyist that everyone needs to buy into their approach to evolution if we want to understand superbugs. Read More ›

A complex network of genes helps plants cope with DNA damage

From ScienceDaily: When a building is damaged, a general contractor often oversees various subcontractors — framers, electricians, plumbers and drywall hangers — to ensure repairs are done in the correct order and on time. Similarly, when DNA is damaged, a molecular general contractor oversees a network of genetic subcontractors to ensure that the diverse cellular tasks needed to protect and repair the genome are carried out correctly and on time. Scientists have known for some time that a master gene named SOG1 acts like a general contractor for repair, coordinating with various genetic subcontractors of the plant cell to mount an effective DNA damage response. But, it wasn’t clear which specific genes were among the subcontractors, nor how SOG1 interacted Read More ›

If DNA were a computer program…

A computer programmer looks at DNA … and finds it to be “amazing” code. From 2006 through 2017, Dutch entrepreneur and software developer Bert Hubert contributed from time to time to a web page where he listed many of the ways the workings of DNA can be likened to coding decisions by programmers. Some of his thoughts: The human genome is about 3 gigabases long, which boils down to 750 megabytes. Depressingly enough, this is only 2.8 Mozilla browsers. DNA is not like C source but more like byte-compiled code for a virtual machine called ‘the nucleus’. It is very doubtful that there is a source to this byte compilation – what you see is all you get. It is Read More ›

Amazing DNA Repair process further detailed

Rockefeller University researchers

found that part of a DNA repair protein known as 53BP1 fits over the phosphorylated part of H2AX “like a glove,” says Kleiner. This interaction helps bring 53BP1 to the site of DNA damage, where it mediates the repair of double-stranded breaks in DNA by encouraging the repair machinery to glue the two ends back together.

New findings shed light on fundamental process of DNA repair

What are the prospects of a DNA self replicating entity surviving with rapid cumulative DNA mutations until it assembles the DNA repair mechanism – by random stochastic processes? Read More ›

Debating Darwin and Design: A Dialogue Between Two Christians

A couple of months ago, I agreed to take part in a written debate with a good friend of mine, Francis Smallwood. Francis, like me, is a commited Christian. Unlike me though, he is also a neo-Darwinist. On his blog Musings Of A Scientific Nature he writes on many different scientific issues, although his primary focus is on Darwinism. I encourage UD readers to check his blog out. As an enthusiastic ID proponent, I obviously think his embrace of Darwinian theory is profoundly mistaken, and equally I think his criticisms of ID are weak. However, he is at least willing to engage in debate with people of opposing view points and is not as dismissive as most Darwinists. Our idea Read More ›
