What role does transfer RNA (tRNA) play in cellular function?

• It stores genetic information
• It helps in protein synthesis
• It protects cells from damage
• It transports nutrients

How did researchers confirm the link between Sam's mutation and RP?

• By conducting a survey of patients
• By using model organisms like zebrafish
• By analyzing family history
• By performing eye examinations

What is the expected outcome of the gene therapy being developed for Sam?
