Bacteriophage T4 structure as per construction from individual PDBs and cryoEMs [1] Escherichia virus T4 is a species of bacteriophages that infect Escherichia coli bacteria. It is a double-stranded DNA virus in the subfamily Tevenvirinae of the family Straboviridae. T4 is capable of undergoing only a lytic life cycle and not the lysogenic life ...
Bacteriophage. Anatomy and infection cycle of bacteriophage T4. A bacteriophage ( / bækˈtɪərioʊfeɪdʒ / ), also known informally as a phage ( / ˈfeɪdʒ / ), is a virus that infects and replicates within bacteria and archaea. The term was derived from "bacteria" and the Greek φαγεῖν ( phagein ), meaning "to devour".
The human thyroid (tan), as viewed from the front; and arteries (red) supplying the gland. The thyroid gland is a butterfly-shaped gland located in the neck below the Adam's apple. The thyroid, or thyroid gland, is an endocrine gland in vertebrates. In humans, it is in the neck and consists of two connected lobes.
Immune electron microscopy (more often called immunoelectron microscopy) is the equivalent of immunofluorescence, but it uses electron microscopy rather than light microscopy. [1] Immunoelectron microscopy identifies and localizes a molecule of interest, specifically a protein of interest, by attaching it to a particular antibody.
Human thermoregulation. As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to adapt to a great diversity of climates, including hot humid ...
Thyroid hormones are any hormones produced and released by the thyroid gland, namely triiodothyronine ( T3) and thyroxine ( T4 ). They are tyrosine -based hormones that are primarily responsible for regulation of metabolism. T 3 and T 4 are partially composed of iodine, derived from food. [2] A deficiency of iodine leads to decreased production ...
The energy used by human cells in an adult requires the hydrolysis of 100 to 150 mol/L of ATP daily, which means a human will typically use their body weight worth of ATP over the course of the day. Each equivalent of ATP is recycled 1000–1500 times during a single day ( 150 / 0.1 = 1500 ), [29] at approximately 9×10 20 molecules/s.
Characteristics. Clostridium tetani is a rod-shaped, Gram-positive bacterium, typically up to 0.5 μm wide and 2.5 μm long. [1] It is motile by way of various flagella that surround its body. [1] C. tetani cannot grow in the presence of oxygen. [1] It grows best at temperatures ranging from 33 to 37 °C.
