Human DNA mapping complete, 6 dead in Sacramento shooting: 5 Things podcast


On today’s episode of the 5 Things podcast: The map of our DNA is finally complete

Health reporter Karen Weintraub explains what that means for humanity. Plus, at least six people are dead after a Sacramento shooting, the Senate Judiciary Committee votes on Ketanji Brown Jackson’s Supreme Court nomination, travel reporter Bailey Schulz looks ahead to this summer’s rental car market and there’s a new champion in women’s college basketball.

Buenos dias. I’m Taylor Wilson and this is 5 Things you need to know Monday, the 4th of April 2022. Today, mapping the human genome. Plus the latest from a Sacramento mass shooting and more.

Here are some of the top headlines:

  1. Germany’s defense minister says Europe must consider ramping up penalties on Russia for boycotting its gas exports. Europe gets 40% of its gas from Russia. Over the weekend Lithuania announced it was stopping Russian gas imports and urged the rest of the region to follow.
  2. A new report from Human Rights Watch is accusing Russia of war crimes during its invasion of Ukraine. That follows similar claims from Western world leaders.
  3. And the Grammys are in the books. Jon Batiste won best album while Olivia Rodrigo took home best new artist. You can find all the winners on USATODAY.com.

Scientists are finally done mapping the human genome. That’s more than two decades after the first draft was completed. Health reporter Karen Weintraub has more on what this means for humanity.

Karen Weintraub:

So we all thought in the early two thousands that they had finished mapping the human genome. The first announcement was that they’d finished a draft and then they’d finished the whole thing. But in truth, they only got 92% and it’s taken them until now to get the last 8%. And the reason involves the technology and the way they were measuring or reading the DNA. They could only read short pieces and then they would use sort of overlapping short pieces to piece together the whole genome. And there are parts that include a lot of repeats. So the genome, the DNA is made up of As, Cs, Ts and Gs and if you had a hundred Gs in a row, you couldn’t see it with a short measurement. So now they can measure a lot longer strands. And so they could see those repeats. So they finally finished the last 8%.
