Answer:
to the restricted section
Explanation:
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.
The answer is autosomes.

a human diploid somatic cell (2n), there are 22 chromosomes
present in two copies and 1 pair of sex chromosomes. This means
there are 23 pairs of chromosomes - 22 pairs of autosomes and 1
pair of sex chromosomes. There are in total 46 chromosomes (23 pairs
in 2 copies: 23 × 2 = 46).</span>
n translation, messenger RNA (mRNA) is decoded in a ribosome to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.
