A nutritionally defective E.coli strain grows only on meduim containing thymine, whereas another nutritionally defective strain grows only on meduim containing leucine. When these two strains are grown together , a few progeny are able to grow on minimal meduim with neither leucine nor thymine. How can this result be explained?
Protist is much more complex then cells of multiceller organisms. Does this mean that the Protist is engaged in more complex activities then multicellular organism and if not why should the Protistan cell be much more complicated?
1. Select a molecule. List the atoms that that molecule is composed of and describe the type of bond that holds those atoms together. Be sure to explain how this bond works. 2. Often, prokaryotic cells exist as simple unicellular organisms, but in some species, prokaryotic cells can grow together in colonies or filaments. In
What distinguishes a eukaryotic cell from a prokaryotic cell? Why embryos are an excellent source for stem cells? Why do cows have the ability to breakdown cellulose into glucose and humans can not digest cellulose?
We are suppose to explain what type of mutation could cause for color variation in certain colonies of E. coli. We first started off with one normal strand of the E. coli bacteria, and after UV light exposure we need to propose a theory of what typeof mutation could cause a single colony to mutate into 5 possible colors (white
Can microbiology assist human genetics? How the alkaptonuria (black urine disease) mutation was identified? Many of the processes that convert one material to another are common to many organisms. Some were preserved during evolution and they are similar among bacteria, plants, animals and humans.
