Bio 1201 Barbee HPV

Select all true statements about the cell cycle:

Barring any controls, the default state of the cell is to divide., Mitosis produces 2n daughter cells from a 2n parent cell.

A bacteriophage contains this self-replicating molecule.

DNA

Which two federal agencies have been most involved in the approval and monitoring of the HPV vaccines?

Food and Drug Administration (FDA), Centers for Disease Control (CDC)

Choose all of the correct statements describing how HPV leads to cervical cancer?

The cell's tumor suppressor gene tp53 produces the protein p53, which is inactivated by the virus and leads to runaway cell division., The cell produces a pRB protein that normally regulates cell division, but the virus produces a protein that binds to it and inactivates it.

HeLa Cells are ________.

cancerous cervical cells

Generally, the longest period of a cell's life cycle is _____________.

interphase

A prophage is always associated with this type of viral life cycle.

lysogenic

Each chromosome lines up on a central plane in the cell during what phase of cell division?

metaphase

The simplest virus is little more than a nucleic acid surrounded by a __________ coat.

protein

Based on its nucleic acid, HPV is this type of virus.

DNA

Choose all of the items that could be found in a virus:

Cells that do not divide for extended periods would be normally in ____ phase of the cell cycle.

G0

Which of the following is a good example of a retrovirus?

Which of the following accounts for someone who has had a lysogenic herpes viral infection experiencing periodic flare-ups of symptoms for the rest of their life?

copies of the virus' nucleic acid permanently maintained in the host cell nucleus

If a virus incorporates its DNA into the host cell genome instead of producing new viral DNA and proteins immediately, it is following the ______ pathway.

lysogenic

The HPV virus uses this type of viral life cycle to replicate itself.

lysogenic

The default response of a cell when it detects DNA damage after cell division is to ___________________.

repair it

The Human Immunodeficiency Virus (HIV) uses this enzyme to back-transcribe its RNA into DNA.

reverse transcriptase

Since HPV can survive for years within host cells, which stages in its replication cycle is the virus capable of delaying?

viral DNA replication, viral protein synthesis, assembly, release
