How Tetracycline works
Tetracycline is an antibiotic.
It works by interfering with the bacteria's ability to make proteins, which are essential for their growth and multiplication. It does this by attaching itself to the bacterial cell's protein-building machinery. It blocks the attachment of a molecule called "tRNA" to this machinery. tRNA is responsible for adding new amino acids, which are the building blocks of proteins, to a growing protein chain. When it prevents tRNA from doing its job, the protein chain cannot grow. This means the bacteria cannot create more proteins, and so cannot multiply. This helps to control the infection and stop it from spreading in the body.
