Question

It is true ddNTPs.....

use during sequencing DMA

lack 3'hydroxide present in dNTPs

none of above 

both of above

 

Expert Solution
Step 1

dNTP( Deoxyribonucleoside Triphosphate) are the building blocks of the DNA and they have the 3'hydroxide group attached on the pentose sugar ring structure and ddNTPs(Dideoxyribonucleoside Triphosphate) lack this feature.

Thus, ddNTPs acts as chain elongating inhibitors( no further chain elongation can occur )of DNA polymerase during the Sanger Sequencing Technique.
