Antibodies (also known as immunoglobulins, abbreviated Ig) are gamma globulin proteinsthat are found in blood or other bodily fluids of vertebrates, and are used by the immune system to identify and neutralize foreign objects, such as bacteria and viruses..
The special protein that attaches to a specific pathogen is called an antibody. Antibodies are produced by the immune system in response to antigens, which are unique molecules found on the surface of pathogens like bacteria and viruses. By binding to these antigens, antibodies help neutralize the pathogen and mark it for destruction by other immune cells. This specificity enables the immune system to effectively target and eliminate a wide variety of infectious agents.
Because they only activate target cells that have special receptors that only work when that specific hormone attaches to it.
Cell-Mediated Immunity
Hormones are chemical messengers produced by endocrine glands and released into the bloodstream. They travel through the body and bind to specific receptors on target cells, triggering a response. This can influence processes such as growth and development, metabolism, and stress response.
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
The special molecule used in protein synthesis is transfer RNA (tRNA). tRNA is responsible for bringing specific amino acids to the ribosome during translation and ensuring that the correct amino acid is added to the growing protein chain according to the mRNA sequence.
Those pathogens that are difficult to grow in the laboratory, requires special media, longer time, and anaerobic condition.
there is no "protein in a prion", because prion is nothing but a protein. The gene sequence of this protein is just normal, with nothing special.
yummy looks good
A chaperone protein is used in the cell to ensure proper protein folding, among other cellular functions.
Your body has special things that get the food that is good and turn it into protein that u could use.
according to information from http://www.rothamsted.ac.uk/notebook/courses/guide/trans.htm " if the RNA polymerase attaches to a special sequence called a promoter, an additional small protein, the factor sigma, will also attach to the polymerase and lock it on the DNA. The factor 'sigma' will only attach itself to the complex DNA / RNA polymerase when the RNA polymerase is attached to a promoter. Another hypothesis is that the factor sigma attaches to RNApol anyway and the enzyme is then able to slide along the DNA until it finds a promoter. It prevents detaching and speeds up promoter location, and decreases the affinity of RNApol for general regions of DNA. " Therefore, the answer seems to be, RNA attaches to DNA through a small protein called the factor sigma once the RNA polymerase attaches itself to a chain sequence called a "promoter". according to information from http://www.rothamsted.ac.uk/notebook/courses/guide/trans.htm " if the RNA polymerase attaches to a special sequence called a promoter, an additional small protein, the factor sigma, will also attach to the polymerase and lock it on the DNA.

Actually there are many promoter and many genes but which gene to be transcribed is decided by sigma factor.
