The best answer for this question would be:
D. Polymerase chain reaction
<span>It is used in molecular biology in order to create small fragments of the DNA. Those copies of the DNA mimic the happenings in the cell. This chain reaction is an efficient technique to further research on crimes.</span>
Answer:
Actually, it’s not the DNA itself cannot leave the nucleus, but the Chromosome or Chromatin. Because, in the nucleus, DNAs are folded into Chromatin or Chromosome. Chromatin or Chromosome just like a rope, and the DNA just the fiber. It’s the rope cannot escape from the nucleus instead of the fibers.
Explanation:
RRNA is used to create a ribosome where translation occurs. So,more rRNA mean more translated proteins. But the cell need one Copy of DNA that contain the whole number of genes that the cell need to live or to make mRNA to make proteins.
