EXPORT MECHANISM: The tRNA must mature inside the nucleus before export. tRNAs are aminoacylated, and only tRNAs charged with an amino acid are exported efficiently. Export occurs when the tRNA is ...
Rush hour never ceases at the nucleus’ border. Gene products begin their lives in the nucleus as strands of mRNA that ship out into the cytoplasm, where they serve as templates for protein synthesis.
Resistance exercise promotes muscle protein synthesis by activating mechanistic target of rapamycin (mTOR). The magnitude of muscle hypertrophy might differ depending on the timing of resistance ...
