Answer 2

a cell inside which a virus replicates

Question 3

virion

Answer 3

the infectious virus particle; the viral genome surrounded by a protein coat and sometimes other layers

Question 4

Answer 4

the protein shell that surrounds the genome of a virus particle

Question 5

nucleocapsid

Answer 5

the complex of nucleic acid and capsid (shell) proteins of a virus

Question 6

lytic pathway

bacteriophage

Answer 7

a virus that infects bacterial cells

Question 8

capsomere

Answer 8

the subunit of a virus capsid

Question 9

retrovirus

Answer 9

a virus whose RNA genome is replicated via a DNA intermediate

Question 10

provirus

Answer 10
