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.
When studying biology and involves more memorizing facts about organisms and how they live because
Answer:
The societal, ecological, or technical constraints that resource managers consider before proposing solutions include the Herculean task of trying to find solutions that don’t worsen or lead to a long-term problem.
Another one is that the mining and use of renewable resources should not exceed regeneration rates as it could lead to scarcity of the said resources.
