What Is 4-Strand DNA & Why Are Scientists So Excited?
We've all learned that DNA is a double helix, but it's more complex than we may think. What other configurations can DNA have? Is Traveling in Our DNA? - http://bit.ly/1ZyqcyY Sign Up...

If you imagine your DNA right now. You’d probably picture that double helix you learned about in school at some point- hopefully. But, it may actually look a lot different. Hey guys I’m Sapna here at DNews. That ladder twisted on itself with bonds between 4 bases- adenine guanine thymine and cytosine, that is the DNA double helix. The thing you were probably picturing in your head. But it’s now thought DNA, at times, may have different configurations. The helix can twist the other way, have a couple extra strands- it can even twist onto itself into some pretty cool shapes. There are 3 biologically active types of the double helix- a , b and z. B-DNA is that recognizable one, it has a right handed twist and it’s the most common in living cells. *(it’s in ...
