Question

Believed to be true until the discovery retro viruses. Dna-infected cells contain virally encoded reverse transcriptase, which uses a(n) rna template to synthesize dna. Thus, their name contains the root retrovirus.

Answer 1

The correct answer will be -true

Step-by-step explanation:

A virus cannot complete its life cycle without a host as they lack the machinery to replicate their DNA. When some host cells in studies were detected with the virus-encoded reverse transcriptase, they termed the virus as the retrovirus.

The root retro was derived from the reverse transcriptase activity of the enzyme which acts by reversing the usual process of RNA synthesis from DNA as reverse transcriptase form DNA from RNA strand.

Thus, true is the correct answer.

Answer 2

Answer;

Believed to be true until the discovery of RNA viruses. Retrovirus-infected cells contain virally encoded reverse Transcriptase, which uses a(n) RNA template to synthesize DNA. Thus, their name contains the root RETRO.

Explanation;

Retroviruses have an enzyme, called reverse transcriptase, that gives them the unique property of transcribing their RNA into DNA after entering a cell.

After infecting a cell, a retrovirus uses an enzyme called reverse transcriptase to convert its RNA into DNA.The retrovirus then integrates its viral DNA into the DNA of the host cell, which allows the retrovirus to replicate. HIV, the virus that causes AIDS, is an example of a retrovirus.
