Chromosome – Definition, Structure, Types, Functions and Diagram
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, Mechanism, Examples and Significance
Parthenogenesis is a type of reproduction where the egg develops into a new individual without fertilization by a male gamete. No fertilization takes place. This is a form of uniparental reproduction and is generally included under asexual reproduction. It is found especially in many invertebrates, while some vertebrates including fishes, reptiles and birds also show … Read more
Red Blood Cells (RBCs): Definition, Structure, Functions, Formation and Life Cycle
Red blood cells (RBCs), or erythrocytes, transport oxygen through the blood. Learn their definition, structure, shape, functions, adaptations, formation, life cycle and disorders.
Types of Plant Cells: Classification, Structure, Functions & Diagrams
Learn the major types of plant cells, including parenchyma, collenchyma, sclerenchyma, xylem, phloem, meristematic and epidermal cells, with functions and diagrams.
Cell Growth: Definition, Process, Regulation and Factors
Cell growth is the increase in cellular mass and size through biosynthesis. Learn its process, regulation, growth factors, cell-cycle role, size control and limits.
Genetic Code – Definition, Codon Table, Properties, and Examples
Genetic code is the set of rules by which the nucleotide sequence present in messenger RNA (mRNA) determines the amino acid sequence during protein synthesis. It is read in groups of three nucleotides, known as codons. Each codon specifies an amino acid or gives a signal for termination of translation. There are 64 codons in … Read more
