Answer: Option D) 8 segments, with the 2 original strands on different segments
Explanation:
During polymerase chain reaction, a double stranded DNA (dsDNA) is selectively and repeatedly copied in the PCR machine.
In the first round, the single piece of double stranded DNA (dsDNA) unwinds in two seperate strands, before complementary nucleotides are synthesized to establish double helix.
In the second round, the two dsDNA yields 4 segments before complementary nucleotides are synthesized to establish double helix.
In the third round, the four dsDNA yields 8 segments before complementary nucleotides are synthesized to establish double helix.
Thus, after 3 rounds, the two original strands are on the 8 different segments of copied DNA.
Well heat rises so when the air pressure is low its hotter. When the air pressure is high its cooler because cool air sinks.
It is false that cytoplasm is a single substance like water.
It consists of 80% water, but has other elements as well.
In surgery yes. it would hurt without it and nobody would get surgery and surgeons would have no job. <span />
