Additionally, P elements often consist of two plasmid components, one known as the P element transposase and the other, the P transposon backbone. The transposase plasmid portion drives the transposition of the P transposon backbone, containing the transgene of interest and often a marker, between the two terminal sites of the transposon.
Cis and trans are defined in terms of the geometric relationships of the two unsubstituted phenyl rings. [23] The two isomers of clomifene have different profiles, where the trans-form has activity more similar to tamoxifen while the cis-form behaves more like 17β-estradiol. [7] Cis is approximately ten times more potent than trans.
Additionally, prior to hormone therapy, transgender men accomplished 43% fewer push-ups than cis men and ran the 1.5 miles approximately 15% slower. After one year of hormone therapy, there was no difference between cis men and trans men in push-ups or run times, but trans men accomplished more sit-ups on average than cisgender men. [10]
Cisgenesis (etymology: cis = same side; and genesis = origin) is one term for organisms that have been engineered using a process in which genes are artificially transferred between organisms that could otherwise be conventionally bred. [2] [3] Genes are only transferred between closely related organisms. [4]
Cis-regulatory elements (CREs) or cis-regulatory modules (CRMs) are regions of non-coding DNA which regulate the transcription of neighboring genes.CREs are vital components of genetic regulatory networks, which in turn control morphogenesis, the development of anatomy, and other aspects of embryonic development, studied in evolutionary developmental biology.
For example (1) a transcribed and translated transcription factor protein derived from the trans-regulatory element; and a (2) DNA regulatory element that is adjacent to the regulated gene. This is in contrast to cis-regulatory elements that work through an intramolecular interaction between different parts of the same molecule: (1) a gene; and ...

These differences can be very small, as in the case of the boiling point of straight-chain alkenes, such as pent-2-ene, which is 37 °C in the cis isomer and 36 °C in the trans isomer. [5] The differences between cis and trans isomers can be larger if polar bonds are present, as in the 1,2-dichloroethenes.
