Does anyone know lots of info on slime molds? If so, could they talk to me on MSN or via email? Thanks
I used to be married to one.NeedBioInfo said:Does anyone know lots of info on slime molds? If so, could they talk to me on MSN or via email? Thanks
Thank goodness. I am so tired of tripping over tomatoes in the dark!NeedBioInfo said:Actually, a while back they took the genes from a lightning bug/firefly and put mixed them with that of a tomato. Creating glow in the Dark Tomatoes.
There's several strategies depending on tools and organism that you working with. To insert DNA You can use a gene gun, a vector ( a viruses or a bacteria such as Agrobacterium tumerfaciens) or liposome. Usually you make a DNA construct that has the gene of interrest, you selection marker (often a antibiotic or toxic agent resistance genes) and other genetic material you want to insert into the cell.NeedBioInfo said:Basically what I want to know is could you put the genes from a slime mold into a multi-cellular organism...and how would you do that..etc
Yes you can put a gene from one species (bacteria, archea or eukaryotes) into the same type or a different type of organism. The firefly luminescens gene is called luciferase and there already glow in the dark plantNeedBioInfo said:Apparently you can take genes from one species and put them into another if what I read below is correct which is whats below
Aren't they already using genes from one species and putting them into others? For example, putting bioluminence genes from say, fireflies, into some other insect, so they glow in the dark...or putting genes from one plant into another to make them more resistent to some type of disease? I'm not fully up on this stuff these days...but I seem to think this stuffs been going on for a while....
It is based on both. The chemicals are important for the formation of the slime colony but certain genes must be turn on or off for this to occur properly.NeedBioInfo said:I also wanted to know about the bio-chemical ability of slime molds, I mean their ability to connect up to each other is based on chemical stuff and not genes right?
There is certain mechanism of defense that would destroyed the DNA but there's way to trick the organism into keeping the DNA. Another problem is protein processing. Not all proteins will be produced, there might be certain feature in a protein that cannot be replicated by the new organism.NeedBioInfo said:Also you'd have trouble putting genes from one species until another because they'd get rejected/destroyed etc right?
Part of that explaination is "pseudo"science. Single cells communicated with chemical signals. When these signals are sense by a population, this trigger the production of certains proteins that is required to go from a single cells state to a community state and then to a forming fruit bodies.NeedBioInfo said:I read this:
. A slime mold is composed of thousands of* amoebas that live individual lives but come together when hungry. When the individual vibrations produced by the hunger reach a critical point, they organize into a coherent entity that can move on the ground as a unit. When it reaches a desired location in the forest the mold sprouts a stalk and body that emits spores from which new amoebas are born, thus renewing the process.
Not all slime molds can form a giant cell which multinucleate. Only the Plasmodial slime molds can. Also, animal cells do not have cell wall, usually plant and fungi have cell wall.NeedBioInfo said:Anyways somebody said
The slime mold lacks cell walls which allows the mass together in one protoplasm (or a single-celled slime mold) or form fruiting structures made up of many cellular slime molds and not just one. The fruiting structures allow the slime mold to release spores, but that doesn't make them fungi--they are still in the kingdom protista.
Does that mean a multi-cellular organism could not have that ability genetically because a multi-cellular organism would have cells with cell walls?
I think somebody got confused when I was talking to them because they were talking about them connecting to each other due to the need to share electrons
