From DNA replication until anaphase, yes
Thanks so much! Are there also cohesins between sister chromatids? Different sources say different things. I have attached 2 images below which contradict each other. First image shows cohesins between sister chromatids and not between homologous chromosomes. The second image shows cohesins between distal parts of homologous chromosomes.

Sorry, cohesins are present between sister chromatids from DNA replication until anaphase. I believe they are also present on the proximal position as they help the spindle diners attach to the kinetochore complex. Cohesin is also found on the distal region

No, homologous chromosomes are not held together by cohesins, but sister chromatids are.

Cohesins are found at distal regions of homologous chromosomes, at chiasmatas.
