What is mitosis? Steps of Mitosis and Importance

Mitosis stages and importance

What is Mitosis? mitosis definition is the division of the mother cell into two daughter cells genetically identical to each other. It is a nuclear division plus cytokinesis and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase. Interphase is often included in discussions of mitosis, but interphase is technically not part of the … Read moreWhat is mitosis? Steps of Mitosis and Importance

Endoplasmic Reticulum : Basics and Functions

Endoplasmic Reticulum

According to Dallmer (1966), Endoplasmic Reticulum is originated from the plasma membrane by the investigation. According to Derobertis (1970), the ER originates from the nuclear envelope. The Endoplasmic Reticulum (ER) is a strikingly complex structure within the cell and has three morphologically distinct regions: Sheets of the nuclear envelope A network of interconnected peripheral ER tubules Peripheral ER sheets … Read moreEndoplasmic Reticulum : Basics and Functions

Active transport: The Specially designed Cell Membrane Mechanism

Active transport Cellular Membrane Mechanism

Active transport is a cellular mechanism by which molecules cross the cell membrane against a concentration gradient, that is, from an area of low concentration to high concentration other with the consequent energy. Typical examples are the sodium-potassium pump, the pump simply calcium or glucose transport. (Check in Biochemistry Dictionary) In most cases the active … Read moreActive transport: The Specially designed Cell Membrane Mechanism

Microbial growth and its Basics

Microbial growth

Microbial growth may be described as occurring in different ways under different circumstances. Microbial growth is usually studied as a population not an individual. Individual cells divide in a process called binary fission where two daughter cells arise from a single cell. The daughter cells are identical except for the occasional mutation. Bacterial Cell: Structure … Read moreMicrobial growth and its Basics

Meiosis: function/stages

Meiosis: function/stages 12

Meiosis, or reduction division, is a process during which exchange of genetic material between the homolog chromosomes (crossing-over and recombination) takes place and such a division of the genetically material occurs the four daughter cells have received each only one set of chromosomes (they are haploid, in contrast to the mother cell which contained homolog … Read moreMeiosis: function/stages
