Phosphodiester bond biology definition
WebRNA, abbreviation of ribonucleic acid, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA (deoxyribonucleic acid) as a carrier of genetic codes in some viruses. WebVideo transcript. - [Voiceover] In the video on the molecular structure of DNA we saw that DNA is typically made up of two strands where the backbone of each of the strands is made up of phosphate alternating between a-- Do some different colors. A phosphate group and then you have a sugar. You have a phosphate group.

The lone pair of electrons of O-atom present in the tyrosine acts as a nucleophile and attacks on the Phosphorus in phosphate of DNA. It causes the shifting of a bond from phosphate to one of the O-atom attached to the ribose sugar forming a hydroxyl group. WebApr 4, 2024 · It is a complex organic molecule consisting of adenine, ribose, and a triphosphate moiety. The energy released during cellular respiration is trapped in the form of two phosphodiester bonds in the ATP molecule. During the hydrolysis of these high-energy phosphodiester bonds in ATP molecules, energy is released, then used for cellular activities.
