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.
DNA is two stranded while RNA is usually one stranded. DNA uses a deoxyribose sugar while RNA uses a ribose sugar. DNA has the base thymine while RNA uses uracil in it's place â¦ .RNA is catalytic, while DNA is only an information storage molecule.hen an RNA is made from DNA, the process is called transcription. Many types of RNA can be made from DNA, including mRNA, tRNA, rRNA, snRNA, snoRNA. Amongst these mRNA is responsible for carrying the directions for making proteins out of the nucleus to the endoplasmic reticulum where protein synthesis occurs.
