Key Difference – T Helper vs T Cytotoxic Cells Lymphocytes are a type of white blood cells with a single round nucleus. They are important defense cells in vertebrates immune system. T cells or T lymphocytes are a subtype of lymphocytes. They are part of the adaptive immunity and are mainly involved in cell […]
Difference Between Troponin and Tropomyosin
Key Difference – Troponin vs Tropomyosin It is important to understand the mechanism of muscle contraction and relaxation properly before learning the difference between troponin and tropomyosin. Muscle fibers are composed of myofibrils. Myofibrils are made up of long proteins arranged in sections called sarcomeres, which are the basic building blocks of striated muscle […]
Difference Between Primary and Secondary Immune Response
Key Difference – Primary vs Secondary Immune Response Humans and other animals live in an environment that is heavily populated by microorganisms. Some microbes are pathogenic and cause various types of infections. The immune system is the natural defense system of our body and the first line of defense designed to fight off against […]
Difference Between Autolysis and Apoptosis
Key Difference – Autolysis vs Apoptosis Multicellular organisms are made from more than one cell. When multicellular organisms grow and develop, the cell number and cell divisions should be tightly regulated to maintain its biological and physical structure. The rate of cell division and rate of cell death are controlled perfectly in multicellular organisms. […]
Difference Between T Cells and B Cells
Key Difference – T Cells vs B Cells White blood cells are an integral part of the immune system. These cells fight against various types of foreign infectious particles including bacteria, viruses, and toxins that make people ill. The low number of white blood cells in the blood stream indicates a weakened immune system. […]
Difference Between Phagocytes and Lymphocytes
Key Difference – Phagocytes vs Lymphocytes The immune system acts against pathogens which enter the body. There are two types of immune cells involved in this action. They are phagocytes and lymphocytes. Phagocytes are a type of white blood cells which ingest foreign particles and destroy them. Lymphocytes are another type of white blood […]
Difference Between Capsid and Envelope
Key Difference – Capsid vs Envelope Virus (also called virion) is an infective particle composed of nucleic acid molecule covered with a protein capsid. Viruses show living as well as non-living characteristics. Two major component of a virus particle are viral genome and the protein coat. The viral genome is packaged inside the protein […]
Difference Between Myofibril and Muscle Fiber
Key Difference – Myofibril vs Muscle Fiber There are three types of muscle tissues; cardiac muscles, skeletal muscles and smooth muscles. Each type has a specific structure and role in the muscular system. Smooth muscles make organs such as bladder, and stomach. Cardiac muscles contract and pump the blood throughout the body. Skeletal muscles […]
Difference Between Ectoplasm and Endoplasm
Key Difference – Ectoplasm vs Endoplasm Protozoa are single-cell eukaryotic organisms. They resemble animal cells and contain major organelles and the cell nucleus. Protozoan’s cytoplasm has two distinct areas called ectoplasm and endoplasm. The outer layer of the cytoplasm is known as the ectoplasm. The inner layer is known as the endoplasm. The terms […]
Difference Between Minisatellite and Microsatellite
Key Difference – Minisatellite vs Microsatellite Repetitive DNA is the nucleotide sequences repeating over and over again in the genome of organisms. Repetitive DNA accounts for a significant fraction of genomic DNA, and there are three main types named tandem repeats, terminal repeats and interspersed repeats. Tandem repeats are the highly repeated sequences which […]
