A) penetration and uncoating
B) synthesis of - strand RNA
C) synthesis of viral proteins

Question

Quizplus · Accepted Answer

The third step in biosynthesis of a + strand RNA virus is the synthesis of - strand RNA. This is because the RNA genome of a + strand RNA virus is first used as a template to produce a complementary - strand RNA, which is then used as a template to produce multiple copies of the + strand RNA.
