Honeybee Genome Sequenced 67
mapkinase writes to let us know about articles in Nature on the completed sequencing of the honeybee genome. From the first article: "Two other insects have already been sequenced: the malaria-carrying mosquito Anopheles gambiae, and one of science's great model organisms, the fruitfly Drosophila melanogaster. Like these, the bee is much easier to manipulate and study than, say, the monkey. But unlike the mosquito and the fruitfly, the bee's social behavior is of special interest." Another article in the same issue clarifies why this sequencing is important: "The genome is helping to reveal some of those [such as the bees' dance language and the division of labor in the hive] mechanisms. For instance, there are 65 spots in the genome that seem to code for short RNA molecules called microRNAs (miRNAs), molecular switches that can turn genes on or off. The researchers found that miRNA activity differs between bees doing different jobs."

Give or take. miRNA goes around turning off certain gene stuff. I'm too lazy to RTFA, but I'd like to know the relationship between miRNA and royal jelly.

Uhh. ohhh. quite the opposite. Error correction is very bad (by IT standards at least) -that is how actually things evolve (since there is no mechanism for modification except mutation - which is an error). On average every single cell in human body has at least one error. Granted absolute majority of them are insignificant (since they happen on non functioning parts of code for this cell)

For me, DNA is like being given a 1 gigabyte ROM containing the complete OS of an unknown system. I am not given the instruction set of the machine...just the raw source. Its up to me to diddle the code- see what the machine does, and from this, deduce how the machine works.
Quite a puzzle.
I envy the guys that are in the middle of this. But I do not envy them the "pressure to show progress" when dealing with such an unknown.

Not so sure about that. The encoding of amino acids in genes is quite well defined (though there are exceptions, such as selenocysteine which is produced when a signal in the 3' UTR changes the meaning of a stop codon).
And protein coding sequences only make up about 1.5% of the genome for humans. Other things in DNA are much less clear, everything in biology is stochastic. Many functional elements are directly involved in protein-DNA interactions w

Yes. There is only so much you can do in a lab to humans. Or for that matter monkeys or mice. However PETA doesn't seem to realize that bees and flys are animals so...
More seriously, we work with model organisms because they are much easier to work with. You can do experiments that would either cost much much more or simply be impossible in a mammal model. Depending on what you are interested in there are lots of popular model organisms: nematodes, flys, bees, zebrafish, xen

For the purposes of creating the reference sequence they essentially ignored them. In the public human genome project the DNA from a handful of individuals was used. The Celera project used mostly the DNA of one individual, Craig Venter, the head of Celera. This does make the reference sequence arbitrary, but so was the block of platinum that was used to define the kilogram. The idea is that you measure differences from the standard.
The rule of thumb is that the sequence of any two individualss differ in about 1 base in 1000. This ignores complications like that fact that women have of two copies of the X chromosome and men have 1 X and 1 Y chromosome, and that whole sections of sequence can sometimes get shifted from one chromosome to another. As the other responder pointed out the variations are a major focus of research, particularly Single Nucleotide Polymorphisms (SNPs) [nih.gov] where 90% of the population have an 'A' in a particulary position and 10% have a 'G'.
