Question

Which of the following is not an advantage of eukaryotic DNA over prokaryotic DNA?

a.) Being diploid preserves variations.
b.) With so much noncoding DNA, eukaryotic DNA is less likely affected by mutations.
c.) Eukaryotic DNA is more likely repaired than prokaryotic DNA.

Answer 1

c.) Eukaryotic DNA is more likely repaired than prokaryotic DNA.

Step-by-step explanation:

• Most prokaryotes have a single circular chromosome which means that they have a single copy of their genetic material. In contrast, eukaryotes have homologous chromosomes hence there are two copies of genetic material leading to more variations.
• Only 1% of eukaryotic DNA is coding in nature so mutations are less likely to harm the organism which is again an advantage.
• The repair mechanism though is evolved very well both in prokaryotes and eukaryotes and many of the mechanisms are also conserved. There are many checkpoints in the cell cycle where the DNA can be repaired. Hence both of them have equal chance to get repaired and eukaryotic DNA has no advantage here over prokaryotic DNA.
