How to draw the Leptotene stage of meiosis in exam is the topic. This is the well labelled diagram of meiosis stage. This is the diagram of Leptotene stage of meiosis. This is a well labelled biology diagram. QUE = WHAT IS LEPTOTENE STAGE ? ANS = The leptotene stage, also known as the leptonema, is the first of five substages of prophase I in meiosis. The term leptonema derives from Greek words meaning "thin threads". A cell destined to become a gamete enters the leptotene stage after its chromosomes are duplicated during interphase. QUE = WHAT IS Meiosis Division ? ANS = In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells, each with half the number of chromosomes as the original parent cell. The two meiotic divisions are known as meiosis I and meiosis II. Before meiosis begins, during S phase of the cell cycle, the DNA of each chromosome is replicated so that it consists of two identical sister chromatids, which remain held together through sister chromatid cohesion. This S-phase can be referred to as "premeiotic S-phase" or "meiotic S-phase". Immediately following DNA replication, meiotic cells enter a prolonged G2-like stage known as meiotic prophase. During this time, homologous chromosomes pair with each other and undergo genetic recombination, a programmed process in which DNA may be cut and then repaired, which allows them to exchange some of their genetic information. A subset of recombination events results in crossovers, which create physical links known as chiasmata (singular: chiasma, for the Greek letter Chi (X)) between the homologous chromosomes. In most organisms, these links can help direct each pair of homologous chromosomes to segregate away from each other during Meiosis I, resulting in two haploid cells that have half the number of chromosomes as the parent cell. #studyofmeiosisdiagram #howtodrawleptotenestage #BiologyDiagram Thanks for watching......
