MEIOSIS!!! THIS is a normal interphase cell. THIS is a normal interphase cell. The nucleus of this cell contains DNA in the form of _______ THIS is a normal interphase cell. The nucleus of this cell contains DNA in the form of CHROMATIN (the long, strandy stuff) THIS is a normal interphase cell. The nucleus of this cell contains DNA in the form of CHROMATIN (the long, strandy stuff) HOWEVER…for this slide show, we are going to represent the cell differently to highlight the process. Instead of THIS… …we are going to draw the interphase cell like THIS …we are going to draw the interphase cell like THIS OK…here we go. The process of MEIOSIS! “normal” diploid cell DNA replicates “normal” diploid cell Prophase I DNA replicates “normal” diploid cell synapsis Prophase I During synapsis, homologous chromosomes pair up and swap chunks of the chromosome (DNA)…this is called CROSSING OVER DNA replicates “normal” diploid cell synapsis Prophase I Metaphase I DNA replicates “normal” diploid cell synapsis Prophase I Metaphase I Anaphase I DNA replicates “normal” diploid cell synapsis Prophase I Metaphase I Anaphase I Telophase I/ Prophase II DNA replicates “normal” diploid cell synapsis Prophase I Metaphase I Metaphase II Anaphase I Telophase I/ Prophase II DNA replicates “normal” diploid cell synapsis Prophase I Anaphase II Metaphase I Metaphase II Anaphase I Telophase I/ Prophase II DNA replicates “normal” diploid cell synapsis Prophase I Metaphase I 4 haploid daughter cells Anaphase II Metaphase II Anaphase I Telophase I/ Prophase II
