Answer:
The correct answer is - middle and late proteins.
Step-by-step explanation:
The viral life cycle involves the gene expression similarly as other organisms however in the viral life cycle there are different types of gene expression present that are early gene expression in the replication cycle that encode proteins are essential for the further expression of the middle and late genes and replication of the DNA.
Middle and late gene expression involve and encode for the proteins that are viral structural proteins that are involved in releasing new viral particles after DNA replication as mention above.
Thus, the correct answer is - middle and late proteins.
