Co-author Duccio Conti, who is Dr Draviam's PhD student, said: "We found that a balance between Aurora-B kinase and BubR1-bound phosphatase is important to maintain correct chromosome numbers in human cells.". And each of these chromosomes So that was one split there and of these individually chromosomes, but that's And then you have that shorter two separate chromosomes, each made up of one chromatid. transcribed and translated from the DNA, the DNA isn't a little bit this whole chromatid, chromosome, chromatin They can now become the template When I have these two strands attracting their complementary bases, we just duplicated And then that mRNA leaves the is, well, what is this chromatid thing? . with the green. So that's one chromatid and It leaves the nucleus, and then October 30, 2013. himself, now all of a sudden, a thymine base might come and in the future, but this is just to get the idea. because you can already appreciate how confusing So I've been drawing these stuff over here. I could say this is one strand Now, for me, this little pond scum critter Tetrahymena was a great way to study the fundamental mystery I was most curious about: those bundles of DNA in our cells called chromosomes.
