Flail chest: A condition that occurs when enough ribs are broken (usually from a crush injury) to compromise the rigidity of the chest wall.On inspiration, the chest wall moves inward instead of outward, and it does the opposite on expiration.lail chest: A condition that occurs when enough ribs are broken (usually from a crush injury) to compromise the rigidity of the chest wall.
The simple summary is that DNA makes RNA, and then RNA makes proteins. DNA, RNA and proteins all consist of a repeating structure of related building blocks (nucleotides in the case of DNA and RNA, amino acids in the case of proteins). In general, they are all unbranched polymers, and so can be represented in the form of a string.
DNA is only important in that it contains the information the cell needs to make proteins. Proteins are simply linear polymers of amino acids that spontaneously fold up into compact 3D shapes following basic principles of chemistry and physics.Humans are made up of approximately 50,000 different kinds of proteins.very cell in your body contains 3.2 billion basepairs of DNA. The sequence of nucleotides in this DNA determines the sequence of amino acids in your proteins. Proteins act as nano-scale molecular machines that carry out countless different tasks in your body.
