Re:

True, there's chemosynthesitic organisms, for example. I still think ancestral mitochondria would've been heterotrophs, because living inside another cell would guarantee such a constantly abundant food source. As long as the host cell remains alive, the intracellular parasite has a constant supply...

It's “a” as it was a heterotroph (derives energy from pre-existing food). Autotrophs produce their own food, hence the word “auto”.

Acid fast organisms such as Mycobacterium have a cell wall made up of glycolipids, in particular mycolic acids and these are resistant to acid staining, only retaining the carbol fuchsin, making them appear red and gram negative. If the organisms look purple, then these have been decolourised and th...

Re: Artificial Meiosis and gamete production

In 2004 a female mouse was born called Kaguya. Born from the genetic material of two mouse eggs, each from different female mice. As an adult Kaguya grew up healthy and even had her own brood when she mated (the conventional way) with a male mouse. Kaguya’s mouse pups were born fine and went on to ...

Look up the gene you want in genebank (on the NCBI website) and order the complete opposite sequence just flanking the region you want to amplify. Alternatively you can paste the sequence into the program Vector NTI, which basically does the same thing.

pretty sloppy to id by cellular morphology alone - esp. when you've never even seen it, sepal Which is why i'm not iding it, I giving advice on gram strain as the OP asked. Look I'm really not interested in arguing with you, you seem bent on flaming me and I've seen you flame others. If you don't k...
