Transcytosis

Transcytosis

Transcytosis It is the transport of material from one side of the extracellular space to the other. Although this phenomenon can occur in all types of cells – including osteoclasts and neurons – it is characteristic of epithelia and endothelia. During transcytosis, molecules are transported through endocytosis, mediated by some molecular receptor. The membranous vesicle migrates through the …

Topoisomerases

Topoisomerases

Topoisomerases are a type of isomerase enzyme that modify the topology of deoxyribonucleic acid (DNA), causing its reluctance as both winding and supercoiling. These enzymes have a specific role in the removal of torsional stresses in DNA so that important processes such as its replication, transcription of DNA into messenger ribonucleic acid (mRNA) and DNA recombination …
