Packaging the DNA After Replication.

Following upon A Little Peek Into DNA Replication, I think it proper to show what happens after it's duplicated. The video below gives a great illustration of what happens.

The video is in two parts. The second part is a time-lapse of a cell dividing into two after replicating its DNA.

While studying DNA in the 1970's, I became convinced that the chromosomes included some form of molecular scaffolding for the DNA, but we did not go into that. Fascinating how it all gets packed away so neatly and compactly.

very interesting.

Absolutely beautiful!

It looks fragile but that's because we are used to things of our size. It is actually stronger than a steel chain per ounce. The bonds that hold it together are quite powerful.

Many thanks Larry. Did not know that.

Fascinating! I love this kind of stuff - the visualizations are invaluable to anyone interested in DNA and it's replication!

Thank you for posting this to Science In An Eclectic Universe!

I sure hope you get to protein synthesis. But you might want to find one that isnt real time, because these go so fast. Anyway, these videos are great. Thanks

I am hesitating on protein synthesis. The process is complex and fascinating. I have to first update and refresh my memory. (I studied it in great detail in the 1970's) I have already watched a few of the videos that clearly show that my information needs to be updated.

WOW! Amazing. And to have the technology to even do this let alone share it with the world! Thanks!

As always... I'm stopping by to visit & enjoy your work, but also to reciprocate your stopping by one of my articles & posting! Thanks!

One of my favorite cartoons! Thanks for posting to The Spiritual Atheists.

One of my favorites also. You're welcome.

Thanks for this, Dennis. Incredibly complex...but nobody said nature was simple. Doctors are still trying to figure out how the human body works at much larger scales than this.

Yes, it is fascinating. I believe this process is continually evolving in natural selection as Darwin indicated. I am simply fascinated how so many different types of dogs come from the wolf.
