How Retroviruses Trigger Cancer

Retroviruses can trigger cancer by changing how host cells grow and divide. These RNA viruses have been shown to cause cancers in species such as chickens, mice, cats, and monkeys.

After infection, the viral RNA genome is reverse-transcribed into DNA. It first becomes single-stranded DNA and then...

Retroviruses are a group of single-stranded RNA viruses with the ability to integrate their genome into the host-cell DNA.

Upon infection into a suitable host cell, the retroviral core enters the host-cytoplasm. The core contains the viral-genetic material and viral-enzymes like reverse transcriptase and integrase.

Once inside the ...
