Answer: After 3 rounds, 8 segments having 2 original strands on different segments will be present.
Explanation:
The polymerase chain reaction selectively and repeatedly copy the double stranded DNA (dsDNA) in the PCR machine.
1st round:
Single piece of double stranded DNA (dsDNA) unwinds in two seperate strands, before complementary nucleotides are synthesized to establish double helix.
2nd round:
The two dsDNA yields 4 segments before complementary nucleotides are synthesized
3rd round:
The four dsDNA yields 8 segments before complementary nucleotides are synthesized.
Therefore, at the end of 3 rounds, the two original strands will be present on the 8 different segments of copied DNA.
The continuous, low-level extinction of species is referred to as mass extinction.
- A widespread and quick decline in the diversity of life on Earth is known as an extinction event.
- A sudden shift in the diversity and abundance of multicellular creatures serves as a telltale sign of such an occurrence. It happens when the rate of diversification outpaces the rate of extinction.
- A mass extinction event occurs when a species disappears far more quickly than it is replaced.
- This is typically understood as the loss of almost 75% of all species over a "short" period of geological time, or fewer than 2.8 million years.
- The Cretaceous-Paleogene extinction, sometimes known as the day the dinosaurs died, is the most well-known of all the mass extinction events.

Answer:
I would probably want to give my child one or two specific traits like intelligence or no inheritable diseases, because I would want my child to have a excellent chance of success in life.
