- Phases of meiosis Prophase I a) DNA coils tightly to form visible chromosomes which appear rod-shaped. Each chromosome is made up of two strands of DNA. One strand of a double-stranded chromosome is known as a chromatid. The sister chromatids are held together by a region called the centromere. b) Nuclear membrane dissolves. c) In animal cells, a pair of centrioles (not visible on these slides) separate and with their newly formed asters (visible) move to each pole. d) Homologous chromosomes pair up. These pairs are called tetrads because there are two chromosomes, but four DNA molecules. Crossing-over occurs.arrow_forwardimagine a giraffe whose diploid is 30.
