During the past several years, scientists around the world have used this method to clone animals. They’ve created about a half-dozen different species, including the famous first sheep, Dolly, along with cows, mice, goats and pigs. Experts say these cloned animals could offer a great deal...
Compared to other types of cells in the body, telomeres in sperm cells are the longest. High telomerase activity was detected in spermatogonia and spermatocytes of embryonic and adult testes in mice and humans (Wright et al., 1996; Martín-Rivera et al., 1998; Pech et al., 2015). Telome...
For safety reasons, active BoNT/X was cloned from two different fragments, one spanning the heavy chain and another one spanning the BoNT/X LC with the activation loop of BoNT/C. This strategy allows for a more efficient and controllable activation of the toxin using Factor Xa, as described ...
The entire ~7-kb fragment was then cloned into the cargo plasmid, pRL277 [42]. The sequence of the inserted fragment was confirmed by DNA sequencing. Conjugal transfer of the resulting plasmid from Escherichia coli to Synechococcus 7335 was performed as previously described [25,38]. Transcon...
On the other hand, when we are looking at a human beings clone it has the same features of appearance. However, a clone is described as “a cell, cell product, or organism that is genetically identical to the unit or individual from which it was derived” (Dictionary). Although clones ...
