Question

____ inject DNA or RNA into the nucleus of a cell to reproduce.

Answer 1

The correct answer is Viruses.

Viruses have DNA or RNA as their genetic material. During the infection the Viruses insert their DNA or RNA into the genetic material of the host cell and then replication takes place inside the host cell and release of new viruses into the host body.

It occurs in six steps:

• Attachment

• Penetration

• Uncoating

• Replication

• Assembly

• Release

Answer 2

Viruses inject DNA or RNA into the nucleus of a cell to reproduce as they cannot reproduce on their own.
