Phosphodiester bond biology definition
WebThe unique 2’-5’ phosphodiester bond may be advantageous because it is less susceptible to degradation caused by 3’-5’ phosphodiesterases. Other advantages of the unique 2’-5’ linkage may be that cGAMP is able to bind multiple allelic variants of STING found in the human population, while other CDNs, composed of only 3’-5 ... WebFeb 27, 2024 · RNA Polymerase Definition. RNA polymerase is a multi-unit enzyme that synthesis RNA molecules from the DNA molecule during the process of transcription. It is responsible for transcribing the genes encoded in DNA molecules into code-able sequences RNA, which further helps during protein synthesis. RNA polymerase plays a vital role in ...
