  1. Here is an extradiotary cool math trick. Try it yourself!


    1. Grab a calculator (You won't be able to do this one in your head)

    2. Key in the first three digits of your phone number (NOT the area code)

    3. Multiply by 80

    4. Add 1

    5. Multiply by 250

    6. Add the last 4 digits of your phone number

    7. Add the last 4 digits of your phone number again

    8. Subtract 250

    9. Divide number by 2


    Do you recognize the answer?


    It's like magic' date=' eh? :cool:[/quote']

    Nope, don't recognise the number. Do you have to have an American phone number for it to work?

  2. Some bacteria are Gram variable and exhibit staining properties in different parts of their growth cycle. eg. a bacterium I have been working with, Thermoanaerobacter ethanolicus, stains Gram positive during early logarythmic growth, and stain Gram negative from a growing culture.

  3. responding to the two previous posts:


    dammit you're right donkey' date=' how could that evade me? in any case i think it's granted what I meant.


    NPK--What i ment was that mRNA gets translated to the effect that the DNA sequence is contains is created into a protein. mRNA is the vehicle for translation, so by that process it does indeed get translated. I think you're missing the point that I am now speaking generally but specifically to what happens--mRNA gets translated.[/quote']


    You might want to read the original post again. I wasn't asking if mRNA gets translated. I know about that. I was asking about tRNA and rRNA.

  4. tRNA and mRNA do get transcripted. They are step 2 in transcription.


    1--DNA is copied and converted to mRNA

    2--mRNA (messengerRNA) goes to ribosomes

    3--protein created based on mRNA message.


    mRNA does get transcriped. It is the courrier that takes the DNA to get copied.

    That's not the point of the thread..it's about translation, not transcription. And mRNA does not get transcribed anyway.

  5. This may sound like a stupid question, but why don't tRNA and rRNA get translated into protein? (I know what role tRNA and rRNA play in cells but what's stopping a ribosome attaching to them etc?)


    Do the Bacterial ones not have Shine-Dalgarno sequences?


    Do the Eukaryotic ones not have a 5' cap?


    Do they quickly fold into their tertiary structure and not expose any binding sites for translation to begin?

  6. Hey, this is my first time in here so i didn't want to start a new thread. I believe I have a weak case of food poisioning. I felt fine last night before bed but when i woke up this morning(I slept longer than usual,about 10 hours) I was horribly nauseated & immediately ran for the bathroom.Sorry for the description but i had the worst diarhea i've ever had,mostly water twice that hour. Then about 30 minutes later i had a heaving fit with little vomit that was brown with bits of food from my last meal which was rigatoni at work. I have a slight fever about 100 but slowly going up. I don't recall eating any meat yesterday & I'm not familar with any food poisioning not caused by meat; can any one help me with this. If this makes any difference I was working with open bags of liquid eggs at work that were splashing around (I work at a food plant).Any input would be great,Thanks.

    Sounds a lot like Salmonella gastroenteritis....Salmonella Typhimurium perhaps.

    The time frame of this is usually 12-36 hours, which seems to fit your account. Apart from meat, eggs and milk are common sources. Symptom can include watery diarrhoea, nausea, cramps, dehydration and vomiting.

  7. I like to think that sugar feeds bacteria and bacteria grow better because of sugar.

    So.. if you take in more sugar' date=' you allow more bacteria in your body to grow, thus you will get sick.


    That doesn't sound right.

    We need bacteria in our bodies to live. And if you have pathogens in your body that are making you sick, you have more problems than just diet! (unless you are eating contaminated food)

  8. When someone has completed a research project and written an article on it, how do they decide which journal to try and get it published in?

    Do they just try one journal, or do they apply to many of them?

    There are so many journals out there, many of which are about the same topics and have lots of content overlap.

    How does the whole process work??
