Which of these processes is LEAST associated with producing genetic abnormalities? A) deletion B) nondisjunction C) replication
Marat540 [252]
The answer is (C) Replication

Though occasional errors could occur in cells during replication; the cells have error checking and proofing mechanisms that reduce the rate of error to one to several million replications in higher eukaryotes.
After all, one mismatch error during replication would not result in major effects. The others choices, however, have higher rates of causing genetic abnormalities.

A particular viral genome can replicate in 8 hours. If you start with 55,000 copies of this genome, about how many copies would
deff fn [24]

If a viral genome can replicate in 8 hours and the starting copies is 55,000, the number of copies after 48 hours would be 3,360,000 copies

<h3>Replication rates</h3>

The starting number is 55,000 and replication happens every 8 hours.

Starting from 0 hours, the genome would 55,000

After 8 hours = 55,000 x 2 = 110,000 copies

After 16 hours = 110,000 2 = 220,000 copies

After 24 hours = 220,000 x 2 = 420,000 copies

After 32 hours = 420,000 x 2 = 840,000 copies

After 40 hours = 840,000 2 = 1,680,000 copies

After 48 hours = 1,680,000 x 2 = 3,360,000 copies
