On the other hand, monolayers of group-V elements, known as pnictogens, including phosphorene, arsenene, antimonene, and bismuthene, recently have gained much attention for their topological aspects, as well as inherent, wide, and tunable band gaps12,13,14,15. Generally, several allotropes are ...
Group I introns and homing endonuclease genes (HEGs) are mobile genetic elements, capable of invading target sequences in intron-less genomes. LAGLIDADG HEGs are the largest family of endonucleases, playing a key role in the mobility of group I introns in a process known as 'homing'. Group ...
In addition to leveraging the existing IKE, IPsec and multicast technologies, a GET VPN topology includes these key elements and features: Group members—The routers that exchange the actual traffic within the VPN are called group members. Group members provide encr...
“morffo” elements (“mobile ORFs in fern organelles”) in the IR region betweenrrn5and the 3’-part of thetrans-splicingrps12gene. Recognizable sequence homologs of morffo2 can presently only be identified inCyclosorus interruptus(accession MN599066, Thelypteridaceae) andHistiopteris incisa(...
