DNA replication film undermines textbooks

Spread the love

From BEC Crew at ScienceAlert: Here’s proof of how far we’ve come in science – in a world-first, researchers have recorded up-close footage of a single DNA molecule replicating itself, and it’s raising questions about how we assumed the process played out.

The real-time footage has revealed that this fundamental part of life incorporates an unexpected amount of ‘randomness’, and it could force a major rethink into how genetic replication occurs without mutations.

“It’s a real paradigm shift, and undermines a great deal of what’s in the textbooks,” says one of the team, Stephen Kowalczykowski from the University of California, Davis. More.

It may not be as random as they think. A subway crowd’s movements may appear random at times, but that is only a surface impression.

But textbooks today are mostly a fraud on the taxpayer anyway. Otherwise, the End of Science rent-a-riot for Darwin would not even be involved so much.

We should be figuring out how to present accurately as much of we can of what we now know – and not how to prevent union teachers from having to learn new stuff at summer school.

    Denyse, interesting report. Thank you.

    I keep saying it but nobody seems listening.
    Ok, let’s say it again:
    They ain’t seen nothing’ yet.
    The most fascinating discoveries are still ahead.

    The reductionist bottom-up reverse engineering research approach takes the scientists on a long and winding road that leads to ‘surprising’ and ‘unexpected’ discoveries, while the Big Data keeps piling up on the clouds.

    Biology research is by far the most fascinating field of serious science these days. Because it’s a WYSIWYG deal.

    Unfortunately some otherwise interesting papers may contain irrelevant text with archaic pseudoscientific hogwash which makes the whole paper look like low grade bovine excreta.

    The evo-devo folks struggle to find a serious case that may satisfy the conditions described @1090 in the thread “A third way of evolution?” to no avail.

    Complex complexity.
    The more we know, the more we have to learn.

    Eric Anderson says:

    First of all, DNA does not replicate itself.

    Secondly, their use of the word “randomness” is completely inappropriate. In fact, what they discovered was another control mechanism that helps to coordinate two separate processes that initially appeared to operate “randomly” with respect to each other.
