Question

Proteins helping in Kinetocore formation of yeast are

• A. CBF$2$ and $Ka{r}^3$P
• B. CBF$2$ and CBF$3$
• C. CBF$3$ and $Ka{r}^3$P
• D. CBF$2$, CBF$3$ and $Ka{r}^3$P

Answer 1

The correct option is D CBF$2$, CBF$3$ and $Ka{r}^3$P

Kinetochores are the proteins which are capable of attaching to the centromeres of the chromosomes. These are DNA proteins. These proteins can bind and move the chromosomes along the microtubules. The proteins which helps in the formation of kinetochore in the budding yeast are CBF2, CBF3 and Kar3P. 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.

Thus, the correct answer is option D.
