Active with Kappa Delta Phi, the National Educational Fraternity, Mario Atoyan was a 7th grade science teacher with the Warwick Public Schools in Rhode Island. Focused on general sciences, Mario Atoyan has a broad range of knowledge and consistently earned ranking as one of his school’s best teachers.
In biology, one of the foundational building blocks is the polymeric molecule ribonucleic acid (RNA), which has roles that encompass gene coding, decoding, expression, and regulation. A nucleic acid that exists alongside DNA, it carries the information that passes on to succeeding generations through genetic inheritance.
The structure of RNA is that of a chain, with a nucleotide at each chain link’s center. These nucleotides contain a base, as well as a phosphate, and ribose sugar. While this structure is extremely similar to DNA nucleotides, the two types of nucleic acids have vastly different roles within cells.
The DNA contains genetic information, encoded within a linear sequence of bases, while the RNA functions as a pathway between DNA to proteins that carry out various structural and catalytic roles within the cell.
Through the process of transcription, a segment of DNA is copied and messenger RNA (mRNA) created. This RNA strand is read by a ribosome in the formation of various proteins. RNAs also have a critical role in the synthesis of proteins and the regulation of genes.
