Question

2. Why did the scientists find Henrietta’s cells so important? (What was different about Henrietta’s cells than other cells scientists had used?)

Answer 1

Henrietta's cells never died/they kept replicating/they are immortal cells

Step-by-step explanation:

Cells typically die after so many replication cycles, her cells did not. They are considered immortal cells. They have an over active telomerase that rebuilds the telomeres after each division. Therefore these cells do not age and can continue replicating
