Well, actually, it did look like an X, before Fukushima.

Actually all chromosomes look kinda like an X immediately before mitosis.  Chromosome 21 definitely doesn't look like a 21, anyway.

Creationists will have you believe it's shaped like a cross, which means Christianity is real or something.

/which has nothing to do with the Christian Science Monitor
//no, really

Doesn't look like an X?

Um, ok.... I guess.

Subby meant to say we don't have letters shaped like Alphabet Soup.

RTFA: They only look like that during mitosis - and each one of those 'X's is actually two copies of one chromosome.

Those are Alphabits. You aren't fooling anyone.

It was called "X," a placeholder for "unknown." Later, its brother chromosome was called "Y," after the next letter in the alphabet.

I never heard this before!  I always just assumed that they were called X and Y because the sex chromosomes aren't neatly paird off and so we differentiate them based loosely on their shapes.

I thought they were just placeholder variables.

Guess what, birds have a "Z" and a "W" chromosome. And ZZ is male, ZW is female. Guess that they started running out of letters.

I guess A through W are just not cool enough.

They're trying to be sensationalist, but they fail.  X and Y look distinct among the paired chromosomes because X looks like an X (like all the other chromosomes) during replication, but Y ... is all stunted and funky and looks like a Y.  Sure, there is 3D structure we aren't aware of, especially outside of replication...is any scientist surprised by this?  Cool research, useful research, but meh.

Tell that to my three year old. He's invented letters that belong in the Time Cube.

It's also ironic that a #2 pencil is not shaped like the number 2.  And you know what else is really ironic?  An F-16 plane is not shaped like an F or the number 16.

There's also an undeniable irony in the fact that a straight A student does not, in fact, resemble an straightened out A.  This is the ultimate irony.
