Reconstructing a Tn10 phage element

When phage λ is grown on a Tn10-containing E. coli host, rare phage that transduce tetracycline-resistance can be isolated. You isolate DNA from λ and from λ-tet and cut each with EcoRI and BamHI and see the following sized fragments on an agarose gel: Tn10 is 9kb long, with one EcoRI site 3.5kb from its left

E.coli

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?

Protists

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?

Water Molecular Structure, Protists and Eukaryotes

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

Microbiology and genetics

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.

Types of cells

Give the name for the type of cells that are simple in structure and are usually surrounded by a thick cell wall for protection and shape.

Why only Eukaryotic cells have evolved into multicellular organisms.

Bacteria never form any sort of grouping that resembles a multicelled organism with an internal division of labor among its cells. Think about the attributes of prokaryotic bacterial cells and the eukaryotic cells of which all multicellular organisms are comprised. Develop some hypotheses explaining why only eukaryotic cells hav
