متن کاملSimilar Triangles, Another Trace of the Golden Ratio
In this paper we investigate similar triangles which are not congruent but have two pair congruent sides. We show that greatest lower bound of values for similarity ratio of such triangles is golden ratio. For right triangles, we prove that the supremum of values for similarity ratio is the square root of the golden ratio.

Retention of cohesins at cluster sites during mitosis raises the possibility that they contribute to transcriptional memory during the cell cycle.
