Lecture´s Description

Mitosis
In this lecture ´´Microtubule Dynamics and Motor Proteins in Mitosis´´ is explained. Section one is about ‘‘Mitosis’’. Initially, educator defines the process of mitosis. In the next few slides, stages of mitosis are pursued.


Mitotic Apparatus
Section two is about ‘’Mitotic Apparatus’’. Educator tells about the mitotic apparatus structural changes in early prophase, prometaphase, metaphase, and anaphase. Each of these changes are discussed in succession. Then mitotic apparatus during metaphase are discussed along with the explanation of three sets of microtubules. Following this, elucidation of attaching chromosomes to microtubules is given. Lastly, centrosome duplication is focused.


Role of Motor Proteins and Dynamic Microtubules
Section three is about ‘’Role of Motor Proteins and Dynamic Microtubules’’. This section is started by the explanation of formation of mitotic spindle during metaphase. Then detailed illustration continues on chromosome capture during late metaphase.


Chromosome Separation During Anaphase
Section four is about ‘’Chromosome Separation During Anaphase’’. Earlier in this section microtubule shortening in anaphase A is explained. Subsequently, spindle elongation in anaphase B is reported.


Role of Microtubules During Cytokinesis
Section five is about ‘’Role of Microtubules During Cytokinesis’’. At first telophase is analysed. Then the process of cytokinesis is discussed in detail. Lastly, mitosis in higher plants is pursued.
