I was
reading this article the other day, just another on the very long list of
articles that I force myself to read in order to get the most thorough
understanding of my field as possible, and I couldn’t help but chortle at the
sense of humor scientists occasionally reveal in their work. I shall quote, if
I may:
Homozygous mutants are semilethal, and adult
escaper flies are uncoordinated and show numerous neurological defects (Figure S1), hence the name fratboy.
OK I’ll translate that for those of you who
have not studied biology since high school.
As you may remember, animals like flies, mice
and humans are diploids, which means that we all have two sets of chromosomes,
which also means two “copies” of our genes. I use quotation marks because that
is not precisely accurate as they are not precise copies, but rather we often
have two different alleles on the same corresponding portion of our chromosome
pair, but that’s a story we don’t need to get into, except to explain the
difference between a homozygous and heterozygous individual.
Having two copies of the same gene can mean
that if one of the two genes is mutated, the individual can sometimes survive
just fine with the one copy of the gene that has remained unchanged. If an
animal has one of it’s genes mutated while the other “copy” is not, it is
heterozygous for that mutation. If, on the other hand both copies of the gene
are mutated it is homozygous for that mutation, and if that gene is important
and there are no other genes that can step up and cover for it, the animal is
screwed.
Scientists usually name genes based on the
problems that the animal has when you remove the function of the gene by
mutation. For example, the gene eyeless in Drosophila is called eyeless
because when it is mutated the flies are born without eyes. In this case,
the flies that have two copies of the mutated gene sometimes die before they
can reach the adult stage. The ones that do survive, however, have neurological
problems including bad coordination, which prompted the researchers to name the
gene fratboy.
Not the best joke in the world after that
tedious scientific explanation, but I was amused.
It is not uncommon for scientists to give
genes weird or humorous names. Probably the most famous is sonic hedgehog,
which was named after, well, Sonic Hedgehog. There are others too, like Van
Gogh, because mutations in this gene cause Drosophila wings to form
these swirling patterns that apparently but the researchers in mind of Van Gogh’s
The Starry Night. Mutations that led to clear larvae earned that gene the name glass
bottomed boat. And the list goes on and on.
Yea, I don't see it either |
So yes, scientists are not as stuffy as you
think people! We can make each other smirk at each other’s papers when we come
across yet another oddly named gene.
And then we find out
that we’re the only ones that find each other funny, and go back to another
funless day – unless we decide to make dry ice bombs, that can brighten up our
moods.
