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.
A DNA molecule is made up of deoxyribose sugar while RNA is made up of ribose sugar. A DNA molecule is double stranded whilst a RNA molecule is single stranded. A DNA molecule only contains the bases; Adenine, Thymine, Cytosine and Guanine.However a RNA molecule contains the bases; Uracil, Thymine, Cytosine and Guanine. DNA is only found in the nucleus of a cell, while RNA is found in the cytoplasm.owever a RNA molecule contains the bases; Uracil, Thymine, Cytosine and Guanine.
