Chromosomes being doubled, chromosomes being lost, chromosomes being cut and pasted around the place, we don't exactly know why that happens.
damage to chromosomes and DNA in human cells.
You have certain chromosomes .
You got your chromosomes down?
So dogs have more chromosomes than foxes, but fox chromosome number 12 is essentially spread across-- bits of it are spread
across three dog chromosomes .
Scrambling of your chromosomes .
We just take the chromosomes , we line them up in a circle.
So the chromosomes changed, and it's different now.
These are the ends of your chromosomes .
So we used to look at chromosomes .
We all have 23 pairs of chromosomes .
This is a disease of faulty chromosomes .
And we can see evidence of whole chromosomes being completely smashed up, stitched back together in all kinds of ways.
So these kind of messed up chromosomes , not just the genes, but sort of the whole chromosomal fuel for evolution, is basically rocket fuel.
So what this shows is your two chromosomes .
--in the form of different chromosomes in the artwork, and everything in between that, including viruses, tumors, parasites.
These are the 23 pairs of normal human chromosomes .
that are similar to the changes in the DNA chromosomes that have people affected with schizophrenia
What being androgen insensitive means is this-- I have XY chromosomes , but my body is unable to respond to so-called masculinizing hormones, resulting in a more female typical appearance
There's still this tendency to link up XX chromosomes with female embodiment and assume all sorts of stuff about the condition of one's corporeality and index
And what we think is going on is that these chromosomes , the black lines, are wrapped up in these loops.
Most of you probably don't know exactly what your chromosomes are.
And we don't know how to get chromosomes into a cell in any logical way.
in almost all cells in our bodies on these chromosomes in the form of the famous DNA, this double helix.
an Indigo Girls cover band The jaded Y chromosomes both going to Stanford where they met Dan Klein and Rob badecker soon
Ironically reading about gametes and the fertilization process and development of chromosomes through sexual reproduction; not that sexy, but reading about the locked eyes of two impassioned lovers
Lo and behold, one of those three dog chromosomes , again, is a hotspot for domestication-- changes associated with domestication.
And she noticed that different segments of DNA would jump around the chromosomes when this happened.
We we took mice and we we we broke their chromosomes in a way that didn't cause cancer
Now, what I'm showing you here are human chromosomes .
There's a lovely word for-- it's called chromothripsis, which basically means chromosomes being shattered.
Variations may appear in a person's chromosomes , genitals, or internal organs like testes or ovaries.
and biological sex, which means delinking assumed continuities between chromosomes , hormones, genitals, reproductive-- and you can see I put non-reproductive there
And if you can see the little letters, you'll see that those two chromosomes have exactly the same nucleotide bases, except for one.
of work out of my lab and 15 others from around the world is the discovery that broken chromosomes disrupt the structure of those hose reels, that DNA,
Is there a little card in your pocket?-- a little record of your chromosomes ?
For anyone who's a biologist, these are homologous chromosomes .
But basically, fox chromosome 12 is divided up-- bits of it-- onto three dog chromosomes .
And because I'm trained as a scientist, I kind of go from chromosomes and hormones through sex and dating to how our brains learn,
these complex patterns of highly condensed repeat things, often near the center of the chromosomes and near the end of the chromosomes .
And what we then find in this Neanderthal is that we find huge segments-- this is 19 million bases here-- where the two chromosomes are identical.
And actually three of those 87 proteins are expressed in the spindle and the parts of the cell that pull the chromosomes apart in cell division.
Yes, have there been any specific interesting insights about the X or Y chromosomes of Neanderthals compared to ours?
So you might remember from high school biology the nucleus is what contains the chromosomes and all the genetic instructions.
yellow nodules, dots, on these chromosomes that are painted with stains.
Well, each chromosome affects potentially thousands of traits that could influence its survival, but when most creatures reproduce, sections of chromosomes get swapped around.
Here, the DNA detaches from the gold, and it integrates itself into the plant's chromosomes .
We then take photos of it, enlarge those photos, and literally snip out the chromosomes and line them next to each other.
Next, I'm going to show you some chromosomes from different breast cancers.
