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 has Thymine, where as RNA has Uracil. RNA nucleotides include sugar ribose, rather than the Deoxyribose that is part of DNA. Functionally, DNA maintains the protein-encoding information, whereas RNA uses the information to enable the cell to synthesize the particular protein. a.1 Differences between DNA and RNA Notes: DNA stores the genetic information, where as RNA uses the information to help the cell produces the protein.
