Question

Describe the typical reproduction cycle of DNA Virus

Answer 1

Reproduction cycle of DNA virus:

• Lytic cycle.
• Lysogenic cycle.

Lytic cycle:

lytic cycle * The lytic cycle Divolues The reproduction of viruses using a host host ull to manufacture more viguses. & The visuses Then burst out of The CORDE

Steps in the lytic cycle;

• Attachment.
• Penetration.
• Transcription.
• Biosynthesis.
• Maturation.
• Lysis.

Attachment:

Attachment to - The phage attaches itself to The surface of the host cell in order to inject its DNA into the cell

Penetration:

Penetration in The phage ewects its DNA isto The cell by penetrating Through The Cell membrare

Transcription:

Transcription con The host ull's DNA is degraded and The calls metabolism is directed to Initiate phage Blosynthesis -

Biosynthesis:

Biosynthesis PrThe phage DNA tell, synthesizing new replicates inside the phage DNA and proteins,

Maturation:

Maturation, onges usum The replicated material assemble isto Fully tuned viaal phages, (Each made up of head, a tail and tail fibres).

Lysis:

lysis in from host The newly formed phages are released The Trfected cell to seek out new cells to Irfect

rit Cycle Po

Lysogenic cycle;

& The lysogenic cycle Trolues The is corporation of The viral genome into The host cell genome. Irrecting it from withir.

* It is characterized by integration Baltviophage Nudele add into the host bacterium genome a formation opi ulou replicon 3 The Baltuia Cytoplasm, ato batolae ad Toruto
