Strains of the human papillomavirus (HPV) that cause cervical cancer express many genes that the cervical cells that they infect
do not. One of these viral genes encodes a protein that binds to and inactivates p53, increasing the chances of the infected cell becoming cancerous. Which of the following is an accurate description of this viral protein? The viral protein is amplifying p53 activity.
The viral protein is a mutagen.
The viral protein is a tumor suppressor.
The viral protein is the product of an oncogene.
A mutagen is any agent or substance that can cause genetic mutation, that may lead to cancer.
Because it is important for cells in the human body to suppress cancer, the body cells including cervical cells has a "guard" that conserves stability by preventing genetic mutation, this "guard" is known as p53. p53 is usually known as tumour suppressor gene
Strains of the human papillomavirus (HPV) must have released a viral protein (mutagen) that would inactivated p53 from carrying out its duties of: DNA repair, DNA damage recognition, and programmed cell death (if DNA repair is impossible) in the cervical cells
There are a lot of functions to the digestive system like absorbing nutrients, get rid of waste but the main function is to process organic molecules so they can enter cells.
Spiders have malpighian tubules<span> to absorb salts and wastes while humans have microscopic subunits in the kidneys called </span>nephrons to filter blood. Malpighian tubules<span> remove wastes from insects by producing urine and solid nitrogenous waste, which are then excreted from the body.</span>
(1) All living things are made up of cells, (2) Cells are the smallest units (or most basic building blocks) of life, and (3) All cells come from preexisting cells through the process of cell division.
