Re: Why is ATP rather than GTP, CTP or TTP the energy currency?

... is prime importance than the ATP is the `chemical you need` , ATP has “faster hydrolysis time” compared to others ( CTP-GTP-TTP ) - Protein covalent bond formations can proceed ` faster rate with ATP ` without any concern for error in 3 dimensional structure of the protein .. GTP is coupled ...

Please comment this theory, is this theory correct?

... to a radical molecule. For example it neutralizes 4 radical molecules and becomes a radical molecule with 4 radicals. Then it sticks to DNA (covalent binding). Because there is no water present there, it stays a radical molecule. When a cell divides, water nears this molecule so it reacts ...

MOLECULAR CLONING

... kinase treatment will participate in the ligation reaction with both their ends having -OH groups. The 3'-OH end of the oligo will form covalent bond with the 5'-phosphate end of the restriction enzyme-digested vector end, but the 5'-OH end of the oligo will have a nick next to the 3'-OH ...

MOLECULAR CLONING

... any way before the ligation reaction. And yes, they need a 5'-phosphate added, by polynucleotide kinase, so the ligase can actually generate the covalent link.
