Question

The specific DNA sequence in the genome of an organism at which DNA replication gets initiated is called

• A. Ori
• B. RNA primer
• C. origin of replication
• D. Okazaki fragment

Answer 1

Answer: (A), (C)

The correct options are
A Ori
C origin of replication

Every species has a unique sequence in their genome, known as the ‘ori site’ or ‘origin of replication’. It is typically a specific number of base pairs long that varies according to species. This is the portion at which the process of DNA replication begins. Prokaryotes have just one such site in their genome while eukaryotes would have multiple ori sites.
