Question
what statement about dna replication is incorrect? question 6 options: dna polymerases catalyze the formation of a phosphodiester linkage efficiently only if the base on the incoming deoxynucleoside triphosphate is complementary to the base on the template strand. to begin synthesis, dna polymerases require a primer with a free 5 -oh group that is already bound to the template strand the reaction requires deoxynucleoside 5 -triphosphates datp, dgtp, dctp, and ttp and a mg2 ion. many dna polymerases have a distinct nuclease activity that allows them to excise incorrect bases by themselves dna polymerases build a phosphodiester bridge up in a reversible manner before pyrophosphate is hydrolyzed by pyrophosphatase
Answer
DNA polymerases build a phosphodiester bridge in an irreversible manner.
- Q:What are the statements provided in the question? A:The statements provided in the question are: 1. DNA polymerases catalyze the formation of a phosphodiester linkage efficiently only if the base on the incoming deoxynucleoside triphosphate is complementary to the base on the template strand. 2. To begin synthesis, DNA polymerases require a primer with a free 5'-OH group that is already bound to the template strand. 3. The reaction requires deoxynucleoside 5'-triphosphates dATP, dGTP, dCTP, and dTTP and a Mg2+ ion. 4. Many DNA polymerases have a distinct nuclease activity that allows them to excise incorrect bases by themselves. 5. DNA polymerases build a phosphodiester bridge up in a reversible manner before pyrophosphate is hydrolyzed by pyrophosphatase.
- Q:Which statement is incorrect? A:The statement 'DNA polymerases build a phosphodiester bridge up in a reversible manner before pyrophosphate is hydrolyzed by pyrophosphatase' is incorrect.
- Q:What is the correct statement? A:DNA polymerases build a phosphodiester bridge in an irreversible manner.
