Blood cells and its types with functions

Blood cells and its types with functions Blood cells are the cells which are produced during hematopoiesis and found mainly in the blood. Blood is composed of the blood cells which accounts for 45% of the blood tissue by volume, with the remaining 55% of the volume composed of plasma, the liquid portion of the […]

Difference between Serum and Plasma 4.58/5 (43)

Difference between Serum and Plasma

Difference between Serum and Plasma       S.N. Characteristics Serum Plasma 1. Definition Serum is the liquid part of the blood after the coagulation. Plasma is a clear and yellowish fluid part of the blood. 2. Composition Serum is the water fluid from blood without the clotting factors. Plasma is the blood fluid that […]

Difference between Replication and Transcription 4.32/5 (34)

Difference between Replication and Transcription

Difference between Replication and Transcription S.N. Characteristics Replication Transcription 1. Definition DNA replication is the process of making two daughter strand where each daughter strand contains half of the original DNA double helix. Transcription is the process of synthesis of RNA using DNA as a template. 2. Purpose To conserve the entire genome for next […]

Differences Between Mitosis and Meiosis 4.23/5 (248)

Differences Between Mitosis and Meiosis

Differences Between Mitosis and Meiosis Mitosis is a process of asexual reproduction in which the cell divides in two producing a replica, with an equal number of chromosomes in each resulting diploid cell. Meiosis is a type of cellular reproduction in which the number of chromosomes are reduced by half through the separation of homologous […]

Differences between DNA and RNA 4.54/5 (141)

Differences between DNA and RNA

Differences between DNA and RNA Here are 17 differences between DNA and RNA. S.N. DNA RNA 1. DNA stands for Deoxyribonucleic Acid. The sugar portion of DNA is 2-Deoxyribose. RNA stands for Ribonucleic Acid.  The sugar portion of RNA is Ribose. 2. The helix geometry of DNA is of B-Form (A or Z also present). […]

Techniques of Virus Cultivation 4.42/5 (294)

Inoculation into embryonated egg

Techniques of Virus Cultivation Viruses are obligate intracellular parasites so they depend on host for their survival. They cannot be grown in non-living culture media or on agar plates alone, they must require living cells to support their replication. The primary purpose of virus cultivation is: To isolate and identify viruses in clinical samples. To […]

Differences Between Cilia and Flagella 4.28/5 (125)

Differences Between Cilia and Flagella

Differences Between Cilia and Flagella Flagella are the complex filamentous cytoplasmic structure protruding through cell wall. These are unbranched, long, thread like structures, mostly composed of the protein flagellin, intricately embedded in the cell envelope. Cilia are slender, microscopic, hair-like structures or organelles that extend from the surface of nearly all mammalian cells (multiple or […]

Different Size, Shape and Arrangement of Bacterial Cells 4.41/5 (355)

Different Size, Shape and Arrangement of Bacterial Cells

Different Size, Shape and Arrangement of Bacterial Cells Bacteria are prokaryotic, unicellular microorganisms, which lack chlorophyll pigments. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Due to the presence of a rigid cell wall, bacteria maintain a definite shape, though they vary as shape, size and […]

Flagella – Introduction, Types, Examples, Parts, Functions and Flagella Staining- Principle, Procedure and Interpretation 4.21/5 (122)

Parts of Flagella

Flagella – Introduction, Types, Examples, Parts, Functions and Flagella Staining- Principle, Procedure and Interpretation Introduction of Flagella Flagella are the complex filamentous cytoplasmic structure protruding through cell wall. These are unbranched, long, thread like structures, mostly composed of the protein flagellin, intricately embedded in the cell envelope.  They are about 12-30 nm in diameter and […]
