Cancers are said to be caused by genetics, meaning the disease originated from the DNA structure. There are viruses that affect the DNA. Examples are hepatitis B virus, Epstein-Barr virus, herpes virus-8 and human papilloma virus. These are the DNA viruses that could cause cancer.
All of the above i think.
Answer:
The correct answer will be option-accurate and complete DNA replication.
Explanation:
The cell cycle of a cell is controlled by the internal checkpoints where the cell cycle halts until the favourable conditions appear. These checkpoints are G1 checkpoint, G2 checkpoint and M checkpoint.
The G2 checkpoint asses that the DNA replication has been completed, all the chromosomes have been replicated and the replicated DNA is not damaged. The cell cycle stops if the replicated DNA is found damaged.
Thus, option-accurate and complete DNA is the correct answer.
Answer:
A group of bacteria that accumulate in layers and secrete an protective extracellular material.
Explanation:
The biofilm is a natural way how the bacteria get together to survive in an ecosystem or in another living thing. They build little by little this kind of building with different layers of bacteria that secrets a polymer, this protection polymer could be useful to protect the colony or to be attach to another cell or to a tissue. In medicine and in veterinarian studies is interesting because can be useful to create a film to protect some injuries.
Answer:
C
Explanation:
The major histocompatibility complex (MHC) is a group of genes whose function is to codify proteins that participate in the immune response, helping the system to <u>recognize foreign substances to develop an immune response</u>.
<u>Histocompatibility or compatibility of tissue </u>is given by self-identifications molecules (antigens) located on the surface of cells, membrane, these molecules are almost <u>unique to each person</u>, letting the body to distinguish self from non-self.
