The meaning of PROPHASE is the initial stage of mitosis and of the mitotic division of meiosis characterized by the condensation of chromosomes consisting of two chromatids, disappearance of the nucleolus and nuclear membrane, and formation of mitotic sp
To answer the question regarding the various stages of meiotic prophase I and the chromosomal events that occur during each stage, we can break it down into the following steps:1. Leptotene Stage: - Description</stro
cell division. Before prophase begins, the chromosomes duplicate to form two long, thin strands called chromatids. During prophase itself, the chromatids condense and thicken and the membrane surrounding the nucleus disappears. In mitosis, prophase is followed by metaphase. See more atmeiosis,mitosis...
Prophase I is the defining stage of meiosis in that it is unique from mitotic prophase and in that it encompasses many of the I unique features of meiosis, including formation of the synaptonemal complex (SC), pairing of homologous (maternal and paternal) chromosomes, and formation of chiasma...
Prophase is the first step in both mitosis and meiosis that prepares the cells for the next stage, the metaphase. What happens during the prophase? Prophase is the first step in both mitosis and meiosis. During prophase, chromatin fibers start to condense and chromosomes become visible under a...
