Question

a scientist is in a laboratory investigating unknown specimens and is trying to determine whether they are viruses or bacterial cells. below are the scientists observations. match the scientists observations with the category (either virus, bacterial cell, or applies to both viruses and bacterial cells) that best applies. select one correct answer in each row.
the specimen has an outer protein coat.
the specimen has its own ribosomes.
the specimen is observed to have genetic material.
the specimen is extremely small.
which of the following occurs during a lysogenic cycle?
a. viral dna is replicated and the host cell is destroyed
b. viral dna is not replicated and the host cell is destroyed
c. viral dna is replicated and the host cell is not destroyed
d. viral dna is not replicated and the host cell is not destroyed

Explanation:

• Las virus tienen una cubierta proteica exterior. Las células bacterianas no la tienen.
• Las células bacterianas tienen ribosomas propios, mientras que las virus no.
• Tanto las virus como las células bacterianas tienen material genético.
• Tanto las virus como las células bacterianas pueden ser extremadamente pequeñas.
• En el ciclo lisogénico, el ADN viral se replica y la célula huésped no es destruida.

Answer:

• The specimen has an outer protein coat: Virus
• The specimen has its own ribosomes: Bacterial cell
• The specimen is observed to have genetic material: Applies to both viruses and bacterial cells
• The specimen is extremely small: Applies to both viruses and bacterial cells
• Which of the following occurs during a lysogenic cycle?: C. viral DNA is replicated and the host cell is not destroyed
