Sister chromatids are not bivalent and therefore cannot form tetrads. The synaptonemal complex is the fusion of the sister chrom
atids at the start of Meiosis I. If two chromosomes have similar positions, structures, and origins they are referred to as sister chromatids. Syanpsis is the fusion of chromosomes at the start of Meiosis I. A chiasma (or chiasmata) is the place where crossing over occurs. Crossing over is an event that occurs in Meiosis II and results in the exchange of genetic information between sister chromatids. 1) True 2) False
cientists would use a control sample that has no DNA from bighead carp in Edna surveillance in order to verify that no DNA has contaminated the gel. It would eliminate certain errors in the experiment. What are some of the things that your DNA can be contaminated with?
