The answer is B between respiration and combustion
Answer:
The correct order is
E. Adsorption
B. Penetration
D. Synthesis
A. Assembly
C. Lysis
Explanation:
Virus can have two reproduction cycle that is lytic and lysogenic. In the lytic cycle first step is virus adsorption or attachment on the host cell surface. The second step is penetration in which the virus penetrated the host cell and injects its genetic material in the host cell.
The third step is synthesis, in this stage, the viral genome gets incorporated and produces viral proteins required for capsid formation. The fourth step is assembly in which viral protein assembled around viral nucleic and form new viruses.
The final step is lysis where the new viruses lyse the host cell to come out of the host cell and infect other cells.
The correct answer is A. Lac repressor.
Lac repressor prevents lac gene which are found in the DNA of Escherichia Coli from being expressed for many times.
Lac repressor is termed as DNA which binds proteins. It allows the expression of genes from coding which are made for proteins to be involved in metabolism of lactose which is in bacteria.
When there is no lactose which is available in the cell, then the genes are being repressed. Lactose are being converted to allolactose if they are available.
