Question
Please choose from this list to fill in the blanks below: prophage, DNA transposon, retrotransposon, integrase, lysozyme, F plasmid, Alu, lambda, plaque, transposase, reverse transcriptase. (Not all of the choices will be used, but some could be used more than once) Most prevalent type of mobile DNA in human Example of a bacterial virus Clear zone on an agar plate where the bacteria have been killed Latent form of a bacterial virus Needed for transposition of typical human retrotransposons Example of a human "SINE" (short, interspersed nuclear element) Use transposase to catalyze their own movement Needed for lysogeny but not lytic infection of bacteria Needed for lytic infection but not for lysogeny Can move from one bacterial cell to another by inserting itself into a plasmid or virusExplanation / Answer
Most prevalent type of mobile DNA in human Alu (The most abundant mobile elements in vertebrates are two types of nonviral retrotransposons called LINES and SINES. The most common SINES in humans frequently contain a site for the restriction enzyme AluI and consequently are called Alu sequences.)
Example of bacterial virus is lambda(Bacteriophage lambda is a virus that infects E. coli. The typical infection cycle results in the lysis of the E. coli cell and the release of about 100 progeny phage particles, each capable of infecting another cell.)
Clear zone on an agar plate where the bacteria have been killed called plaque.
Latent form of bacterial virus prophage (A prophage is a bacteriophage genome inserted and integrated into the circular bacterial DNA chromosome or existing as an extrachromosomal plasmid. This is a latent form of a phage, in which the viral genes are present in the bacterium without causing disruption of the bacterial cell. )
Needed for transposition of typical human retrotransposons integrase.
Example of human “SINE”( short interspread nuclear element) Alu.
Use to transposase to catalyse their own movement integrase
Needed for lysogeny but not for lytic infection of bacteria integrase (Integration of ? DNA into host chromosome. If the lysogenic pathway of phage ? development is chosen, the crucial step to form the prophage is integration of the viral genome into the host chromosome. This reaction is catalyzed by the phage-encoded Int protein, also called integrase.
Needed for lytic infection but not for lysogeny lysozyme( lytic infection produce virus particle in bacteria and release after lysis if bacterial cell for that lysozyme enzyme is required)
Can move from one bacterial cell to another by inserting itself into plasmid or virus F plasmid( F plasmid is plasmid of fertility which is responsible for conjugation in bacteria.
