At the first the egg cell was haploid cell (1n) , then after fertilization occurs, it became a diploid cell (2n), after that cell is in interphase where growth and DNA replication occurs(almost 90% of the cell cycle time),in interphase cell became 4n, the cell enters mitosis with the same quantity of DNA (4n), and then at telophase(X)Somebody explain ths question plz
It did thank u so muchhAt the first the egg cell was haploid cell (1n) , then after fertilization occurs, it became a diploid cell (2n), after that cell is in interphase where growth and DNA replication occurs(almost 90% of the cell cycle time),in interphase cell became 4n, the cell enters mitosis with the same quantity of DNA (4n), and then at telophase(X)
the number of DNA(4n) is halved to (2n) for the two Daughter cells to have the same identical number of DNA as the body cells
so the answer is D, hope that helped you!
You are welcome!It did thank u so muchh
37. When an antigen enters for the first time primary response takes place. to make antibodies cells undergo clonal selection to produce a colony of cells that are specific for the antigen. Most of these clones differentiate into the plasma cells, also called effector B cells (which produce the antibodies) , and the rest are memory cells. which survive for longer. so there are memory cells made and still present till 20 days
