As long as the lymphocyte is not activated or "turned-on", nothing happens to the viral DNA. But if the lymphocyte is activated, transcription of the viral DNA begins, resulting in the production of multiple copies of viral RNA.
How long can you hold your breath? 10 seconds? 30 seconds? 400 years? Breathing is both voluntary, and involuntary. This means that you can control it if you want to.

stolon
A long slender stem running along the surface of the ground, arising from the axil of a leaf, whose function is to enable rapid vegetative propagation in an area. Runners are found, for example, in strawberries and creeping buttercup.

The term chromatid is used so long as the daughter centromeres remain in contact with one another. As soon as they separate (anaphase of mitosis and anaphase 2 of meiosis), the expression daughter-chromosome is substituted for chromatid.
Centric fusion: Fusion of the long arms of two acrocentric chromosomes [13,14,15,21,22] into a single chromosome having lost the short arms at the same time. Most often occurs as 21/21, 13/14, and 14/21 translocations.
Many cloned animals have not lived long enough to generate good data about how clones age. Appearing healthy at a young age unfortunately is not a good indicator of long-term survival. Clones have been known to die mysteriously.
