Question
Proteins helping in kinetocore formation of yeast are
CBF2 and Kar3 P
CBF2 and CBF3
CBF3 and Kar3 P
CBF2, CBF3 and Kar3 P
Solution
D.
CBF2, CBF3 and Kar3 P
The kinetochore assembles on the centromere and links the chromosome to microtubule polymers from the mitotic spindle during mitosis and meiosis. Its proteins also help to hold the sister chromatids together and play a role in chromosome editing. CBF2, CBF3 and Kar3P are the kinetocore proteins used in yeast. These three are the proteins which are commonly called as factors. These proteins helps in the binding of the chromosome to the microtubules by attachment with different complexes.
