T-cells are a type of white blood cell that circulate around our bodies, scanning for cellular abnormalities and infections.
Answer:
No, telomerase is not an oncogene. It prevents the senescence that would occur due to shortened telomeres, but the cell proliferation might still be mitogen-dependent.
Explanation
telomerase is not responsible for causing deregulation while oncogenes cause deregulation .
Telomeres length shorten after the cell division which stops them to divide again and cell die.
Telomerase prevents this decline in some kinds of cells, including stem cells, by lengthening telomeres, and the hope was that activating the enzyme could prevent senescence.
Answer: Homologous chromosomes are the pairs of chromosomes that having same gene sequence, equal length of arms and centromere location. Homologous chromosomes have two homolog one come from male parent and other come from female parent.
Explanation:
These chromosomes Are formed for the purpose of genetic variations. They are called homologous because when two same structured exist it form pair together
