When an E. coli cell is infected by multiple phages, what route of infection (lytic or lysogenic) will the phages take? Why?
Artyom0805 [142]

Answer:

When an E.coli cell is infected by multiple phages,they will take either lytic or lysogenic pathway.

Explanation:

When lambda phage bacteriophage infects an E.coli,it can either undergo lytic cell growth and lyse the host cell or enter lysogenic pathway.

The operator region of lac operon in E.coli contain single repressor binding site whereas the lambda operators O_{L} and O_{R}  each contains 3 repressor binding sites (O_{L_1} ,    O_{L_2},O_{L_3} and O_{R_1},O_{R_2},O_{R_3})  that are differently occupied under different conditions.

The differential affinity of lambda repressor for the three binding sites in these operators play an important role in the maintenance of lysogenic state of lambda prophage in E.coli.

The lytic development occurs in cells infected with lambda phage that carry  C_1 gene.

In contrast,lysogeny will occur in bacteria that infected with lambda phage that harbor a deletion of Cro gene.

what would happen to an enzyme if the temperature and pH changed significantly beyond the enzyme`s optimum level?
allochka39001 [22]
<span>If the PH and temperature changed significantly beyond the enzyme optimum level it will become denatured and then the enzyme would not work.
The Enzyme is a biological catalyst which speeds up a reaction. The Enzyme has molecules which act upon as substrates and then it converts those substrates into different molecules which are called products.
The study of the enzyme is known as enzymology, and they are well known to catalyze more than 5,000 biochemical reaction types.</span>
