And now with no suspects, the cops and Jeffries began to collect DNA samples from local men, but they came up with no matches.
Oh yeah, that gets us into all the ethical questions that we're going to get into in a second surrounding DNA. But yes, this was the UK in the 80s and there were no laws around DNA sampling yet. The cops had no leads in this murder case until someone overheard a local baker named Colin Pitchfork bragging that he had submitted a friend's DNA.
So the cops grabbed the dude and he was the perfect match.
Yeah, they brought out the torches and pitchforks for Pitchfork and he went down and DNA evidence became a thing because in truth, it actually took years for American courts to figure out how and when it was acceptable to use DNA evidence. There were ethical questions that needed to be addressed if they're going to be databases of people's DNA.
Then those databases and laboratories had to then meet the standards that were established. But there was no getting around it. This was a huge leap forward as DNA evidence enabled law enforcement to solve cases that had gone cold decades ago.
The DNA Identification Act of 1994 authorized the FBI to create a national DNA database that compares DNA found in crime scenes to the DNA of violent offenders.
Yeah, it was a huge win, and TV writers everywhere rejoiced, and mic drop moments were unleashed on a hungry public.
Yeah, TV writers had plenty more to write about as real science continued to catch up with science fiction. The next big achievement came with the mapping of the human genome in 1990.
Yeah, and it was a really big project, like a really big project. The project was headed by Francis Collins, and it took 13 years and sequenced 3 billion chemical pairs and maps all the genes encoded in human DNA.
Short answer. Genes are segments of your DNA. Those segments, genes, are responsible for our unique physical characteristics. In short, genes are the units of hereditary traits and contribute... to the traits an organism inherits from its parents. DNA is the complete string of these segments all strung together in a double helix.
Okay, let's start by differentiating between cloning plants and animals. Many plant cells are totipotent, meaning each cell has the potential to regenerate into a whole new plant. Very often, cloning a plant requires little more than just snipping a branch and allowing it to grow into a whole new plant. Cloning animals is different.
That is when scientists make an exact copy of something using its DNA, that is to say, no sex needed. Some organisms already do this in nature, like starfish, which can regenerate an entire new body from just an arm. Most animals can't do this. But with the scientists' help, just about any living thing can make an exact copy of itself.
In 1996, scientists in Scotland successfully cloned a sheep named Dolly.
Dolly was the only lamb to survive out of 277 attempts.
Yeah. In fact, until Dolly, many scientists believe mammals just couldn't be cloned. But they can. In fact, right now, there are companies that can clone a pet for you. So if your favorite kitty dies, you can literally get them back. And once again, a panoply of ethical questions have arisen.
In truth, the bigger question is, should humans be cloned? And the answer is, yes. We think primates have already been cloned, and researchers in South Korea and Michigan have cloned a human embryo, but that was only for research purposes. Countries are passing laws about human cloning. Like all things DNA, is mired in ethical questions.
Yeah, look, we'll get to China in a minute because they are players here. But each of these developments raises a new set of ethical questions. Genealogical databases, that's where tons of private health information is stored. They could be hacked by bad actors. And I don't mean like Nick Cage.
I mean, somebody leaks your DNA on the Internet and now insurers don't want to cover you because you're prone to cancer or whatever.
That is so true. And you know what? I saw his movie Pig recently, and it was really weird and good. I haven't seen it.
Okay, I haven't heard of Cocomelon yet.
