Purpose The purpose of this lab experiment was to utilize the various RNA database websites provided to discover the other types of RNA and their characteristics, the features of tRNA and the secondary structures of RNA. Introduction Before the recent findings in RNA, RNA molecules were subdivided into three groups: Ribosomal RNA (rRNA), messenger RNA (mRNA) and transfer RNA (tRNA). These three groups are said to be the most common forms of RNA. They hold a prominent part of the functioning of a cell and the protein synthesis. RNA (or ribonucleic acid) is a nucleic acid that is present in all living cells. It is also utilized in forming proteins inside of cells. RNA is what aids DNA in translating and transcribing the genetic information. …show more content…
tmRNA is also known as 10Sa RNA and by its genetic name SsrA. In trans-translation, tmRNA and its related proteins tie to bacterial ribosomes which have slowed down amidst protein biosynthesis. For instance, when achieving the finish of a messenger RNA which has lost its stop codon. The tmRNA is versatile because it reuses and rescues stalled ribosomes, adds a proteolysis-inducing tag to the incomplete polypeptide, and encourages the degradation of the aberrant messenger RNA. tmRNA rescues ribosomes that are stalled by damaged messenger …show more content…
The tRNA molecule has a specific folded structure with three hairpins that create the illusion of a clover. One of the loops consist of a sequence called the anticodon. Every tRNA has a certain amino acid attached to the end of it. tRNA is a type of RNA that assists messenger RNA in decoding a sequence into a protein. c. Examining Secondary Structure of tRNA Discussion: All in all, this experiment conducted introduced me to more than three types of RNA. Each of these proteins are important in protein synthesis. RNA is a polymeric molecule that consist of a few nucleotides. With the use of the A. N. Belozersky Institute database, the secondary structure of the protein was predicted above. 4 ligands were seen in the 3D structure of the tRNA shown above. Secondary structures are the 3D form of local segments of proteins. Secondary structures also defined as the pattern of the hydrogen bonds between amino hydrogen and carboxyl atoms in the peptide
