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.
I believe the correct answer is C. Nektons include bony fish and squid.
Monomers are molecules whose linkage between them form polymers.
<h3>What are monomers?</h3>
Monomers are molecules that have a low molecular mass.
<h3>Characteristics of monomers</h3>
- When many monomers come together through chemical bonds they form a polymer, which is a macromolecule.
- Natural monomers allow the formation of biomolecules found in living beings.
- Carbohydrates, for example, are macromolecules that are created from the bond established by monosaccharides (monomers).
Therefore, we can conclude that polymers, in short, are chains of monomers -generally joined by covalent bonds-.
