<span>The chaparral is characterized by sparse, rough terrain and nutrient-poor soil meaning that no single resource is overly abundant. Therefore, a varied diet allows an animal to make use of a wider selection of the resources that are available to it and thereby thrive.</span>
<h3>What is DNA MTase activity and PEC assay?</h3>
- Based on the exciton energy transfer (EET) effect and site-specific cleavage of restriction endonuclease, a highly sensitive photoelectrochemical (PEC) test for MTase activity and inhibitor screening was created.
- The test was created by fusing CdSe quantum dots (QD) with probe DNA that was tagged with Au nanoparticles (NPs).
- The photocurrent signal was drastically reduced as a result of the potent EET effect between Au NPs and CdSe QDs.
- A sensing region on the pDNA allowed it to recognise the target DNA (tDNA) and hybridise with it to create a DNA duplex.
- The photocurrent signal was restored once the EET was broken by the site-specific cleavage of HpaII, which allowed the DNA duplex to be broken and Au NPs to be released.

To test for side effects and rare effects (the bigger the sample size, the more likely that wired things may occur)
<span>The answers are visual spectrum and pupil. The visible light spectrum is a narrow band of frequencies ranging from 390 to 780 wavelengths long. These wavelengths are detectable by the eye and the different length corresponds to different colors.
The pupil determines how much light can enter the eye. It dilates and constricts depending on the amount of light available.</span>
