WebJan 27, 2024 · Post-transcriptional and post-translational modifications are very important for the control and optimal efficiency of messenger RNA (mRNA) translation. Among these, methylation is the most widespread modification, as it is found in all domains of life. These methyl groups can be grafted either on nucleic acids (transfer RNA (tRNA), ribosomal RNA … WebThe gene control in eukaryotic cells, particularly during differentiation is one of the most extensively studied areas in biology with special reference to molecular mechanism. The genes control the synthesis of various proteins in various cells which finally lead to differential gene expression.
