What is Prophase I? Definition of Prophase I Prophase I is the initial stage of meiosis I, characterized by the exchange of genetic material between paired homologous chromosomes through homologous recombination, leading to increased genetic variation. This phase encompasses five sub-stages: leptotene, zygotene, pachytene, diplotene, and diakinesis. Prophase I Glossary of Terms By understanding these … Read more
What is Prophase II? Definition of Prophase II Prophase II is a stage in meiosis II where chromatin condenses into distinct chromosomes, the nuclear envelope disintegrates, centrosomes migrate to opposite poles, and the spindle apparatus forms, preparing the cell for subsequent division. Unlike Prophase I, no crossing over of chromosomes occurs in this phase. What … Read more
What is Prometaphase? Definition of Prometaphase Prometaphase is a stage in eukaryotic cell division characterized by the breakdown of the nuclear envelope and the attachment of microtubules to chromosomes, preparing them for alignment during metaphase. What Happend in Prometaphase? In prometaphase, several key events take place during eukaryotic cell division: Overall, prometaphase sets the stage … Read more
What is Liposome? Liposomes, derived from the Greek words “lipo” (fat) and “soma” (body), are spherical vesicles characterized by at least one lipid bilayer. These structures are primarily composed of phospholipids, notably phosphatidylcholine, and often incorporate cholesterol. Other lipids, such as those present in eggs and phosphatidylethanolamine, can also be integrated, provided they are congruent … Read more
What is Integral Protein? Definition of Integral Protein An integral protein is a type of protein that is permanently anchored within the cellular membrane, often spanning its entire width, and plays crucial roles in various cellular functions due to its specific functional domains. Integral Protein Types Integral proteins, a pivotal component of cellular membranes, can … Read more
What are Daughter Cells? Definition of Daughter Cells Daughter cells are the cells resulting from the division of a single parent cell, either through the process of mitosis, where they inherit identical genetic material, or meiosis, where they receive half the genetic content. Characteristics of Daughter Cells Daughter cells are the end products of cellular … Read more
What is Prokaryotic Ribosomes? Definition of Prokaryotic Ribosomes Prokaryotic ribosomes are molecular complexes consisting of ribonucleic acid (RNA) and proteins that facilitate protein synthesis within prokaryotic cells, such as bacteria and archaea. Ribosome Subunits Ribosomes, intricate molecular complexes responsible for protein synthesis, consist of two essential subunits in prokaryotic cells, collectively referred to as the … Read more
What is Diploid Cell? Definition of Diploid Cell A diploid cell is a cell that contains two complete sets of chromosomes, one inherited from each parent. Features of diploid cells Diploid cells are integral to the genetic architecture of many organisms. Here are the salient features of these cells: Diploid cells in Human body In … Read more
What is Embryology? Definition of Embryology Embryology is the scientific study of the formation, development, and growth of embryos and fetuses within organisms. History of Embryology The historical trajectory of embryology is a testament to humanity’s enduring quest to understand the origins and development of life. This journey, spanning diverse civilizations, offers a rich tapestry … Read more
What is Embryonic Stem Cell? Definition of Embryonic Stem Cell Embryonic stem cells (ESCs) are pluripotent cells derived from the inner cell mass of a blastocyst, an early-stage embryo, capable of differentiating into any cell type within an organism. History of Embryonic Stem Cell The history of embryonic stem cells (ESCs) is marked by pioneering … Read more
