1 A hematoma is a collection of blood outside of a blood vessel. 2  Symptoms of hematomas depend upon their location and whether adjacent structures are affected by the inflammation and swelling associated with the bleeding.
What is RNA? Ribonucleic acid, or RNA is one of the three major biological macromolecules that are essential for all known forms of life (along with DNA and proteins). A central tenet of molecular biology states that the flow of genetic information in a cell is from DNA through RNA to proteins: âDNA makes RNA makes proteinâ.
messenger RNA (mRNA) is a copy of genomic DNA that codes for a specific protein. DNA cannot leave the nucleus and enter the cytoplasm, where ribosomes make the proteins. There â¦ fore there need to be a way to get the code that's on the DNA to the ribosomes so that it can become protein. mRNA is the solution.ll cellular organisms use messenger RNA (mRNA) to carry the genetic information that directs the synthesis of proteins. In addition, some viruses use RNA instead of DNA as their genetic material; perhaps a reflection of the suggested key role of RNA in the evolutionary history of life on Earth.
