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.
Like DNA, mRNA consists of four bases. The bases in mRNA are grouped into sets of three called codons. Transfer RNA (tRNA) consists of the same four bases. Just as in the previous step, you want to find complementary bases.hat Happened Window : The RNA molecule you've just transcribed consists of nine bases. In a real cell, the RNA molecule would be anywhere from 100 to 10,000 bases long. An RNA molecule transcribed from DNA is called messenger RNA, or mRNA for short.The mRNA now moves away from the DNA and leaves the cell's nucleus.
