22.(c)The host cell lyses, releasing the replicated pathogen.
Bdellovibrio bacteriouorus species are extremely small, highly motile, Gram-negative, soil inhabiting bacteria that attack and replicate in other Gram-negative bacteria.
Bdellovibrio divides to replicate and then leaves via a final lysis of the host's cell wall and membranes same as in lytic cycle where cell lysis releases viral progeny.
23.(a) protection of phage genetic material.
proteins protect phage genetic material, secure injection of the phage nucleic acid into the bacterial cell,
Protein(capsid) part of the bacteriophage does not enter the bacterial cell wall, only genetic material enters cell.

Place the following events in the process of transduction in the correct order. Not all labels are used. Transducing particle Bacterial cell lyses, releasing phages. Foreign bacterial DNA integrates into the host genome by homologous recombination. Bacterial DNA A transducing particle attaches to a specific receptor on a host cell. Replaced host DNA- Bacteria multiply with new genetic material. Bacterial cell forms endospore and goes dormant. Bacterial DNA is injected into a cell.

which of the following regarding transposition is true
Which of the following regarding Transposition is TRUE? Transpositon requires the Ffactor. Transposition is a form of horizontal DNA transfer through the cutting and relocation of genetic material from one cell to another. Transposition is a form of genetic change and amplification, Transposition requires a sex pilus. The main difference between genetic replication and transposition is genetic material is duplicated during replication and is only moved during transposition Which of the following...
