Question

How does a eukaryotic cell distinguish the end of a broken chromosome from the end of an intact linear chromosome?

Short answer

A eukaryotic cell distinguishes the end of a broken chromosome from the end of an intact line by detecting telomeric DNA at the end.

Step-by-step solution

Explanation of Concept

Eukaryotes are organisms whose cells have a nuclear envelope surrounding the nucleus.They are organisms that belong to the Eukaryota or Eukarya group, and their name comes from the Greek and. Eukaryota is one of the three realms of life, the other two being bacteria and archaea.

Step 2: Distinguishing Chromosome and Damaged DNA ends

When the telomeric repeat is complementary to the DNA sequence and the overhang is long enough, the matching strand can be replicated normally. Hence, the presence of telomere repeats allows all cells to differentiate between natural and damaged chromosome ends.
