Question

5 multiple choice 2.5 points a disadvantage of working with hela cells in a laboratory is that: hela cells spread easily and can infect other cell lines hela cells die off after a few generations hela cells do not survive well on different surfaces hela cells are difficult to obtain

Explanation:

To solve this, we analyze each option:

• Option 1: HeLa cells are known to be highly invasive and can contaminate other cell lines by spreading easily. This is a well - known disadvantage.
• Option 2: HeLa cells are immortal and can divide indefinitely, so they do not die off after a few generations. Eliminate this option.
• Option 3: HeLa cells are relatively easy to culture on various surfaces. Eliminate this option.
• Option 4: HeLa cells are widely available and not difficult to obtain. Eliminate this option.
