Texas A&Mâs four-year graduation rates have significantly improved from 38.4 percent to 50.9 percent since 2001, while six-year rates stand at 80 percent. The university is making considerable advances in achieving the Action 2015: Education First target of 12,500 degrees granted per year, she adds.
Transfer RNA, or tRNA, is a specialized RNA molecule that brings amino acids to the ribosome for protein production. In eukaryotic cells, tRNA is made by a special protein that reads the DNA sequence and makes an RNA copy, or pre-tRNA.
To ensure consistency of the protein synthesis process, all tRNA molecules having the same anticodon sequence always carry one and the same amino acid residue. The process of translation begins when the mRNA molecule binds to the ribosome. The start codon (the first one!) always calls for methionine amino acid.
