WebIts two steps such as prophase-1 and prophase-2. The nuclear envelope disappears at the end of prophase I, allowing the spindle to enter the nucleus. Prophase I is the longest phase of meiosis, typically consuming 90% of the time for the two divisions. Long phase divided into substages (Leptotene, zygotene. pachytene, diplotene, and diakinesis).
Web10 sep. 2024 · Synapses are composed of three main parts: The presynaptic ending that contains neurotransmitters The synaptic cleft between the two nerve cells The postsynaptic ending that contains … Web8 aug. 2024 · The human body is made up of trillions of somatic cells with the capacity to divide into identical daughter cells facilitating organismal growth, repair, and response to the changing environment. This process is called “mitosis.” In gamete production, a different form of cell division occurs called “meiosis.” The outcome of meiosis is the creation of …
WebSolution. In meiosis I, synapsis formation occurs in the zygotene stage of prophase-I. It is the second stage of prophase-I. During this stage, the chromosomes start pairing together and this process of association called synapsis. Such paired chromosomes are called homologous chromosomes. This synapsis is accompanied by the formation of ... Web7 aug. 2016 · In meiosis I, homologous chromosomes of a single cell separate to achieve the desired result. Each resulting daughter cell receives one genomic set of chromosomes. In meiosis II, the chromatid separation takes place. As a result, four haploid daughter cells are produced at the end of meiosis.
