Question

watch the animation on vaccination, and then answer the question.
the animation describes two methods of generating a vaccine. evaluate the following statement:
of the two methods, only the tobacco plant method requires expression of viral genes.
this statement is true because the viruses
this statement is true because the tobacco
harvested from the egg method are inactive.
plant method transfers genes from one
this statement is false because gene
organism to another.
expression is also required by the viruses for
this statement is false because both
their replication within the eggs.
vaccines are capable of stimulating an
immune response.

Explanation:

In the egg - based vaccine production method, viruses are grown in eggs. Viruses, being obligate intracellular parasites, need to express their genes (for example, to produce viral proteins for replication) within the host cells (in this case, the cells in the egg). Just like in the tobacco - plant method (where viral genes are expressed in plant cells to produce viral proteins for the vaccine), gene expression is also a part of the virus growth process in the egg method.

Answer:

This statement is false because gene expression is also required by the viruses for their replication within the eggs.
