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 and RNA DNA is what makes up our genes, and is only present in the nucleus. RNA is what is used to copy DNA and transport it to ribosomes to make proteins based on the RNA transcript. It is also used as enzymes in splicing, protein synthesis, and others.All nucleic acids contain 3 key parts a base, a sugar, and phosphate groups. The 5 major bases are adenine, guanine, cytosine, thymine (DNA only), and uracil (RNA only).The difference between single nucleotides of DNA and RNA is the sugar.NA and RNA DNA is what makes up our genes, and is only present in the nucleus.
