The three day Viagra you don't need to take on an empty stomach. The weekend love pill. Man, I bounced on that bitch for three days straight, thanks to Cialis. Like being 16 again, except this time I know what I'm doin'.
A full set of sister chromatids is created during the S subphase of interphase, when all the DNA in a cell is replicated. Identical chromosome pairs are separated into two different cells during mitosis, or cellular division.
Sister chromatids (with -tid at the end), are two identical (= exactly the same) parts (Chromatids) arising from replication of a chromosome. (In the figure here next the sister chromatids A1 and A2 are an exact copy of each other, as well as the set B1 and B2, whereas homologs A's and B's show small differences).
