The correct answer is: The virus has entered the genome of the bacterial cell and is in the lysogenic stage
Lytic cycle and lysogenic cycle are types of a bacteriophage’s life cycle.
Lytic cycle can be divided in stages:
• Attachment-viruses binds to the receptor on the surface of bacterial cell, usually it uses tail for the attachment
• Entrance-virus injects its genome material (DNA or RNA) into bacteria cell
• Replication and protein synthesis-virus uses mechanism of bacteria to replicate its genome and produce proteins. As a consequence, a huge number of new viruses are formed
• Lysis- viruses express protein for the bacterial lysis (bacterial cell expand and burst) and hundreds of new phages are released.
Lysogenic cycle is different: bacteriophage’s genetic material-prophage, integrates into the host bacterium's genome or forms circular replicon in the bacterial cytoplasm. Bacterium continues to live and reproduce normally but prophage can be transmitted to daughter cells.
Answer:
All eight phenotypes are possible but parental phenotypes will be more in number
Explanation:
In the cross MmDdPp X mmddpp eight types of offspring are possible because MmDdPp will produce eight types of gametes. These offspring are:
- MDP/mdp
- Mdp/mdp
- mDp/mdp
- mdP/mdp
- MDp/mdp
- mDP/mdp
- MdP/mdp
- mdp/mdd
In absence of linkage, the genes would have assorted independently producing all the eight types of offspring in equal number. Hence the phenotype ratio would be 1:1:1:1:1:1:1:1.
If the genes are linked they will show the tendency to get inherited together and crossing over will not take place up to the expected degree. Hence fewer recombinants will be produced and more parental type offspring will be produced.
