Question

what is the function of dna polymerase iii in replication in e. coli?
○ to unwind the dna helix during replication
○ to seal together the broken ends of dna strands
○ to add nucleotides to the 3 end of a growing dna strand
○ to degrade damaged dna molecules

Explanation:

DNA polymerase III is the main enzyme involved in DNA replication in E. coli. Its key role is to add nucleotides to the 3' end of a growing DNA strand. Helicase is responsible for unwinding the DNA helix. DNA ligase seals together the broken ends of DNA strands. Nucleases are involved in degrading damaged DNA molecules.

Answer:

to add nucleotides to the 3' end of a growing DNA strand
