whatever is a dummy variable that you can replace with other variables. Be sure to indent the statements to repeat in the loop. We need to have at least one condition to implement the loop and make ...

R loops consist of RNA–DNA hybrids that accumulate at preferred regions all over the genome, such as pericentromeric DNA, telomeres, ribosomal DNA or transcription termination regions. R loops are an ...

G-protein-coupled receptors are membrane proteins that are regulated by a small family of arrestin proteins. During formation of the arrestin–receptor complex, arrestin first interacts with the ...

Supercoiling and looping can transmit mechanical stress along the DNA backbone that can promote the separation of the strands of the double helix at specific distant sites, exposing the DNA bases, ...

Negative feedback is a universal control mechanism that lets a system's output throttle its input. If an engine revs up, negative feedback tapers its power source. But if the engine slows down, it ...
