When egg white is heated, it hardens and is opaque. This cooking process cannot be reversed, but hard-boiled egg white can be di
marshall27 [118]

Answer:

Generally proteins are denatured at high temperature.Therefore when  the egg is hard boiled they are denatured since eggs are protein,  the 3-dimensional  structure of protein is lost, and it is replaces with tangled meshwork of polypeptide chains .This is because the  orderly arrangements of  disulphide bonds in proteins  are disrupted , which  results in the formation of inter chains bonds among   disulphide bonds, making the protein molecules to link together.This explains the reason for the 3-D structure disruption  and formation of  a macro molecule.

However,   the  addition of reducing agent ,  breaks the covalent disulphide bonds.   While detergent breaks the interchain bonds among the disulphide bonds.  (The noncovalent bonds),These combined effects untangled the  mesh networks of polypeptides formed, and reduces the hardened nature,

Predict the most likely outcome of culturing transformed E. coli in the presence of tetracycline.Justify your prediction.
My name is Ann [436]

Answer:

E.coli is a bacterium which is preffered for transformation due to its rapid growth and high efficiency of introduction of DNA molecules into cells.

Tetracycline is an antibiotic used to treat several infections such as cholera, plague, brucellosis, and malaria etcetra.

Plasmid is a small, extrachromosomal DNA molecule present in cell which is seprated from chromosomal DNA and have ability to replicate independently.

When a plasmid resistant to tetracycline and kanamycine is inserted into E.coli, the process is called transformation. E.coli might not be able to survive due to absence of plasmid but the transformed strains having antibiotic tetracycline and kanamycine will probably be able to survive it.

Hence, the culture of bacteria carrying plasmid will be able to survive only.
