These mosquitoes are defined as a separate species from those living on the surface (from which they evolved) by several important differences, both behavioral and biological. They die much more easily in the cold, do not hibernate in the winter, and feeds on mice, rats, and humans (the parent...
"A new species of mosquito in London
The new species of mosquito Culex pipiens molestus recently formed in, and is endemic to, the London Underground rapid transit system. It most likely speciated from the surface population Culex pipiens, although it is now genetically dissimilar enough to be...
I'll gladly join in that dialogue. RNA as such is also not passed down from parents to offspring. It simply does not exist for long enough for that to happen. For this reason, RNA changes cannot cause change over several generations, only DNA can.
In addition, RNA can never be incorporated...
Not to nitpick, while thats close to true, the 'D' in DNA and 'R' in RNA actually denote a difference in structure, so the DNA and RNA molecules are actually different. There is such a thing as double stranded RNA (dsRNA, some viruses use it), but it is structurally different from DNA. In terms...
I'm not a doctor or even a med student, but, based solely on my impression of the wikipedia article, acquired hypertrichosis is linked to cancer (which is caused by mutations in DNA, not RNA). If you meant the inherited form, it is caused by mutations in the DNA of the parent from whom it was...
Um, I don't really understand what you mean in most of your post, however I would like to point out that RNA is sorta like a temporary copy of DNA that only exists for a short time, so if there is variation between the RNA two organisms produce, it means there is a difference in their DNA.
Of course, but I know more about history and tradition a lot more than I do about theology. I didn't mean to imply anything disrespectful, I just think someone else will be best equipped to explain that.
Uh ok... the main one isn't really that good of a story, but sure :)
I was visiting St. Isaac's cathedral in St Petersburg, Russia, and I hadn't really wanted to go because I thought going to churches to sightsee was pointless (I was 12, I have a better appreciation for architectural beauty...
This is just an assumption, but I would say maybe it had an alternate benefit? They are trying to figure out what it actually changed atm. It does not have to be beneficial to the citrate process specifically. The mutation would have happened with or without citrate, but whether it would have...
So this is what the researchers found: sometime between the 31,00th and 31,500th generation the bacteria became able to use citrate for meatabolism. Normally, E.coli bacteria cannot do this bacause they lack protein(s) (for which genes are the blueprints) to bring the citrate inside the...
I'm not 100% certain on this, but I think the difference between Eastern Orthodox and the other Christian churches is that icons are used as a focus for the veneration of a specific saint or religious figure, while in the other churches, if images are used at all, they are more expressions of...
I actually found this forum a while back, and have been reading a lot of the posts, but I'm just now joining in the discussion. I'm intensely curious about religion and people's perceptions of God or their supernatural deity(or deities) of choice. Religion wasn't really part of my life while I...
So this experiment has been running for a long time, but I just found it and thought it would be interesting to hear what people think about it.
I haven't posted enought to link to the page directly, but the experiment can be found by googling "lenski experiment e.coli", and their wikipedia...
