Answer:
I know that the nucleus is the big boss of the cell, and the chlord past is ONLY in plants
What do Enzymes enable cell reactions to do? proceed at normal temperature, lowers the activation energy needed for reactions to being. ... normal active energy is too high so this allows the reactions to occur at body temp.
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
and
each contains 3 repressor binding sites (
and
) 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
gene.
In contrast,lysogeny will occur in bacteria that infected with lambda phage that harbor a deletion of Cro gene.
