Question

Proteins known as cohesins hold sister chromatids together prior to anaphase, where they are broken down by enzymes, allowing each sister to move to opposite poles to the cell. What is the rather unimaginative name of the enzyme which cleaves cohesin?​

Separase✔✔✔✔

➡️➡️➡️⬇️⬇️⬇️⬇️In mitosis, cohesin is cleaved in metaphase, which triggers anaphase.

In meiosis, however, the cohesin is cleaved earlier in the cell cycle, leaving only the centromere to hold the chromosomes together.

This is important as, in meiosis, the chromosome arms must be free from their sister chromatids to allow crossing over (swapping of genetic information), ensuring genetic variation amongst offspring.

Answer 2

${\huge {\mathfrak {Answer :-}}}$

➡️ $<b>Separase. </b>$

➡️ It is also known as separin, is a cysteine protease responsible for triggering anaphase by hydrolysing cohesin, which is the protein responsible for binding sister chromatids during the early stage of anaphase.

That's it..
