Question

Suppose a new species of bacterium is discovered. t contains a form of DNA pol IlI that can add new nucleotides to either the 5 end or the 3' end of an existing strand All other properties of the enzyme remain unchanged How would DNA replication in these bacteria differ from normal replication?a.Helicase would no 1onger be required for replication.b.Both new strands could be synthesized continuously like the leading strand.c.DNA gyrase would no longer be required for replication.d.The same polymerase molecule could synthesize both strands at the same time.

Answer 1

Answer:

Both new strands could be synthesized continuously like the leading strand

Explanation:

The DNA pol III is an enzyme that can add nucleotides to create the new DNA strand while reading one of the main strands of DNA from 3' to 5'. This new type of DNA pol III that can add nucleotides to either the 5' or the 3' end will make two continuous strands as when the DNA pol III reads the DNA from 3' to 5' and not one continuous and one discontinuous strand as when the normal DNA pol III reads the strand from 5' to 3'.
