Which of the following build(s) new strands of DNA?View Available Hint(s)for Part ADNA polymerasesThe leading strandThe origins of replicationThe lagging strandParental DNA
Solution
DNA polymerases are the enzymes that build new strands of DNA. They do this by adding nucleotides one by one to the growing DNA chain that are complementary to the template strand.
The leading and lagging strands refer to the two newly synthesized DNA strands. The leading strand is synthesized continuously in the 5' to 3' direction, while the lagging strand is synthesized discontinuously in the 5' to 3' direction as well.
The origins of replication are the particular sequences in a genome at which replication is initiated.
Parental DNA refers to the original strand of DNA that is being replicated.
So, the answer to your question is DNA polymerases.
