The DNA sequence that is recognized as the termination region in prokaryotes is:
AT-rich region
GC-rich region
Replication fork barrier
Inverted repeat sequence
The termination region in prokaryotes contains an inverted repeat sequence, which means that the sequence on one strand is inverted and complementary to the sequence on the other strand. This creates a hairpin loop structure that causes the replication machinery to stall and eventually dissociate.
Option 4 is the correct answer.
