  1. Good day students are mr malika and I want us
  2. to focus on today's lesson topic which is known as
  3. Then my talks is cell division.
  4. I know that you're not familiar with the topic but
  5. this is one of the most interesting topics to ever
  6. know. So as I indicated that today's topic is my
  7. toes. Is cell division.
  8. What is mitosis?
  9. Cell division?
  10. Well today we are going to explore about my two
  11. choices. Yeah, yeah.
  12. Yeah, mitosis is a cell division that results in the
  13. deployed number of chromosomes.
  14. Yeah, this is known as the chromosome.
  15. Ladies and gentlemen, if you look at it, we have
  16. the true sister committed.
  17. They overlap each other and when they overlap each other,
  18. the post is called causing over takes place in the
  19. middle. We have the kinetic oh and we also have
  20. the same to me.
  21. Um This thing it is referred to us the process
  22. of causing over because the exchange of the genetic material
  23. will take place in this face.
  24. Remember we have the tsunami Sina Tomio complex which will
  25. form around the sister committees so it can be able
  26. to transfer the genes during this closes, then moving on
  27. to the importance of my taxes.
  28. Lady ST James.
  29. We are now going to explore the importance of my
  30. horses. The first one is it replaces the one outsells
  31. mm It is responsible for the growth and development.
  32. Yeah. And now ladies and gentlemen, as we are moving
  33. on, we are moving on to the stages of tomatoes.
  34. Is the first stage is the interface.
  35. We have the poor face.
  36. We have the meta face.
  37. We have the interface and we have the tailor face.
  38. So we are gonna now look into more details and
  39. the stages of mitosis.
  40. As we indicated that we have the several stages in
  41. mitosis. So for you to remember this, we have to
  42. create a pneumonic.
  43. and pneumonic is like a song like.
  44. So the monomer sonic that I have prepared for you
  45. is I.
  46. P MET I for interface.
  47. P. For poor faith and form interfaith, A.
  48. For anna face and T.
  49. For taylor faith.
  50. Yeah. Mhm.
  51. These are the stages of mitosis.
  52. Ladies and gentlemen.
  53. The first stage is known as the interface and the
  54. second stage is the poor face.
  55. And in the stage of the profits.
  56. As indicated here we have the we have the process
  57. known as the causing over During the process of crossing
  58. over. What will happen is this the system committees will
  59. overlap and they will become the homologous chromosomes.
  60. So they will contain the genetic material from the father
  61. and the mother.
  62. Yeah. So we all know that the mother and their
  63. father have 23 chromosomes.
  64. So a human being has 46 pairs of chromosomes.
  65. So there are 46 chromosomes in the human being.
  66. So where do they come from?
  67. 23 from the father and 23 from their from their
  68. mother. And moving on to the what to the process
  69. of matter face during the matter is what happens.
  70. What happens is that the harmonicas chromosomes.
  71. They align in the equator of the cell.
  72. This process is known as the the random assortment of
  73. the of the chromosomes.
  74. And then after the random assortment of chromosomes we will
  75. move to the N.
  76. F. A.
  77. Stage in the N.
  78. F. A.
  79. Stage. What happens the those those chromosomes will will separate.
  80. They will become the white the comma teeth they will
  81. be pulled towards they think towards the end of the
  82. of the pole.
  83. Yeah. We must consider that the sentence special fibers will
  84. will begin to to eliminate in the in the sale
  85. and also as remove all.
  86. We'll move to the tele face stage.
  87. So in the tele face, what happens is that the
  88. chromosome arrived at the opposite poles and begin and begins
  89. to do.
  90. You condense.
  91. Buy it.
  92. Ladies and gentlemen, as you can see in the dark
  93. one here there's a spindle fibers.
  94. They disappeared and now we are resulting in what 22
  95. cells as I indicated that what mitosis is there the
  96. cell division that results in the word in the deployed.
  97. As you can see now there are two cells that
  98. are be that are being formed and we can also
  99. see that what that might might not expendable fibers breaks
  100. down. It breaks down this thing you can see form
  101. from the diag one after the tailor face.
  102. We have the process that happens which is known as
  103. the psychokinesis.
  104. So in the same token this is we know that
  105. the cleavage for all will happen.
  106. And when the cleavage power happens, we know that the
  107. two cells will will separate.
  108. One will become to the other side and one will
  109. come to the other side.
  110. So yeah, when this thing constricts, one will notice that
  111. a nuclear has formed.
  112. Unlike in the tele face, it was beginning to to
  113. disappear. Now it has worked, it has it has formed
  114. and these are the status of of mitosis that one
  115. must know and must know definitely.
  116. Okay. And now ladies and gentlemen, I'm moving on to
  117. the first stage of my choices which was not included
  118. in those stages, which was the the puffy the matter
  119. face, the interface, the tale of Faith.
  120. Now I'm going to the first one, which is what
  121. which is the interface.
  122. The interface stage is divided into three phases, which is
  123. the G.
  124. One, the G two and the S.
  125. Stage. So during the G.
  126. One it is responsible for what it is responsible for
  127. for gold.
  128. And then in the sP in the S speech it
  129. is responsible for for the DNS in cases and in
  130. the due to stage it is responsible for what for
  131. gold and preparation for for my toes is so my
  132. two cents needs to go all in that what in
  133. those stages that I mentioned area, which is I.
  134. P. Made interface poor face, meta face on a face.
  135. And then in the in your face distance spends longer
  136. time in the interface stage.
  137. So students.
  138. Yeah, there is in why this spend longer time in
  139. there, Interfere stages because of the those three Faces, which
  140. is the word, the G one, G 2 and then
  141. the S.
  142. Stage. Now, ladies and gentlemen, thank you for today's lesson.
  143. Here is what you must write as your homework in
  144. order to determine that you have grasped whatever that I
  145. mentioned earlier.
  146. So number one, you must write five stages of mitosis.
  147. Why is my toes is important and draw the chromosome
  148. structure? And if you do not understand, don't worry, I
  149. will help you come to my office and I can
  150. help you as we must all pass.
  151. The main goal here is to what is for all
  152. of us to pass.
  153. Thank you.
