Lysosome – Definition, Structure, Functions, Types
Lysosomes are membranous, spherical sacs that are made up of enzymes. They are acidic hydrolase enzymes that are capable of digesting cellular macromolecules. The membrane of the lysosome helps keep its internal compartments acidic, and also separates the digestion enzymes and the cells’ other components. Lysosome enzymes are created by the proteins of the endoplasmic reticulum , which is then enclosed in vesicles created by the Golgi system. Lysosomes are created by budding out of in the Golgi complex.
Inclusion Bodies – Definition, Classification, Examples
What are Inclusion Bodies? Inclusion bodies are thick in size, spherical and aggregated proteins typically found inside the cells of protokaryotes thanks to the overexpression of heterologous proteins. Inclusion bodies comprise small particles that are freely suspended and floating in the cell wall. This is why they are also known as inclusions of the cytoplasm. … Read more
Nucleoid – Definition, Functions, Characteristics
The Nucleoid (meaning it’s like a nucleus) is an irregularly-shaped part of the prokaryotic cell which is home to all or most part of the gene material. The chromosome of a protokaryote is circular and its length is big in comparison to cell dimensions, which is why it has to be compressed to be able to fit. Contrary to the nucleus in a prokaryotic cell, it’s not protected by the nuclear membrane.
Chromosome – Definition, Function, Structure, Types
Chromosomes are a collection of tightly coiled DNA that are located in the nucleus of virtually every cell of our body. Humans possess 23 chromosome pairs.
Chromosome Abnormalities – Types, Mechanism, Detection
A chromosome disorder, also known as Chromosome Abnormalities is caused by an alteration in the size or the structure of chromosomes.
Cell Signaling – Definition, Types, Functions
What is Cell Signaling? Three Stages of Cell Signaling Cell signalling can be defined simply as the creation of a “signal” by a single cell. The target cell then receives this signal. In actuality, signal transduction is stated to involve three phases: Types of Cell Signaling Pathways Cell signalling plays a crucial role in enabling … Read more

Transfection – Definition, Types, Principle, Applications
Transfection refers to the introduction of foreign DNA (non-host genome genetic material) into a cell. The primary goal of transfection is to modify the host genome in order to express or inhibit the production of the linked protein. The primary purpose of this page is to provide readers with a thorough explanation of the fundamental … Read more
Parthenogenesis – Definition, Types
What is parthenogenesis? – Parthenogenesis Definition Natural Parthenogenesis The regular, continuous, and natural occurrence of parthenogenesis in the life cycles of certain animals is known as natural parthenogenesis. There are two types of natural pathogenesis: complete and incomplete. (i) Complete parthenogenesis (ii) Incomplete parthenogensis Complete and incomplete type of natural parthenogenesis The two forms of … Read more
