DNA / RNA


1/23/17

The first stable semisynthetic organism has been created.

Can you spot the error in this story?
(hint: it's right at the beginning)


The first paragraph ignores the fact
that 5methylcytosine is part of the genetic code.
So now we're up to 5 bases.
They also ignored the fact
that RNA is also part of the genetic code.
RNA substitutes uracil in place of thymine.
So that is a 6th base that they ignored.

Those wacky scientists. Now look at what they've done:
They've gone and expanded the genetic code ...
and just when I had finally gotten those 5 bases memorized.

Three 16-year-old girls win Google's global science competition

They discovered a naturally occurring bacteria in soil called Diazotroph.
They determined that the bacteria could be used to speed up
the germination process of certain crops, like barley and oats, by 50 percent,
potentially helping to fulfill the rising demand for food worldwide (4:45)
