Final answer:

DNA ligase is the enzyme most likely to be mutated in a cell strain where Okazaki fragments do not join properly.


Explanation:

DNA ligase is the enzyme most likely to be mutated in a cell strain where the joining of Okazaki fragments is impaired. DNA ligase plays a crucial role in the DNA replication process by catalyzing the formation of phosphodiester bonds between adjacent DNA fragments, such as Okazaki fragments during lagging strand synthesis.
