Itâs easy to understand how insomnia might be linked to depression. âChronic sleep loss can lead to a loss of pleasure in life, one of the hallmarks of depression,â explains Stanford University research psychologist Tracy Kuo, PhD. âWhen people canât sleep, they often become anxious about not sleeping.
There is a clear need to design an improved controllable plasmid attachment system to add functional moieties to plasmid DNA in order to monitor and improve gene delivery and also for DNA vaccination to improve immunogenicity. We have devised an improved system based on ODNs of 100% locked nucleic acid (LNA) . LNA is an analogue of RNA or DNA. The term LNA is used to describe both nucleotide monomers, in which the ribose ring is constrained by a methylene linkage between the 2â²âoxygen and the 4â²âcarbon, and also ODNs that contain one or more monomers of LNA.
Report Abuse. b) to cleave nucleic acids at specific sites Bacteria contain restriction enzymes as a defense against viruses. The restriction enzymes cut up the nucleic acids or the genetic material of viruses so they will be unable to integrate themselves within the bacterial DNA.Restrition enzymes are also used to insert different genes into plasmid vectors so that those specific genes may be reproduced for experimental needs. to join nucleotides during transcription b to cleave nucleic acids at specific sites c to add new nucleotides to the growing strand of DNA d to join nucleotides during replication e to repair breaks in sugar-phosphate backbones.
