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.
mRNA or messenger RNA is a nulceic acid that acts as a transferring agent. It copies the information encoded in the DNA in the form of sequences of the four nitrogen bases using the DNA as a template. However, like all other RNA, mRNA does not use the base Thymine like DNA does, instead it and all other RNA use Uracil.t copies the information encoded in the DNA in the form of sequences of the four nitrogen bases using the DNA as a template.
