The correct answer option is C. They are target specific.
Explanation:
We are to determine whether which of the given statements is true about antibody.
Antibodies are a type of proteins which are present in the body to defend the foreign attacks that are in the form of antigens.
These proteins have a basic structure which consists of two pairs of polypeptide chains that are linked covalently via disulfide bonds.
Each antibody recognises one specific antigen and this feature is called as antibody specificity.
Cancer cells affect the cell cycle by not following the checkpoints and dividing abnormally and not getting destroyed by the process of apoptosis leading to the formation of tumours.
In the cell cycle during the mitotic phase the cell divides resulting in two daughter cells and segregation of DNA occurs in this. In cell cycle, there are checkpoints of signalling pathways which determine when the cell has to grow and divide. The healthy cells follow the cell cycle.
Explanation:
Cancer cells become immortal and result in faulty proteins which are not required by the system. The cancer cells grow uncontrollably and are abnormally shaped.
The cell cycle has check points at S phase and G2 phase before it enters the Mitotic phase of division. Normal cells follow the checkpoints.
