Homework Answers
Correct answer:- (c) polymerases
Explanation :- in DNA replication, one strand of new DNA is
produced as a continuous chain (also called the leading strand),
while the other strand of new DNA is made in short discontinuous
pieces (called the lagging strand).
- DNA Polymerase III is the enzyme that connects nucleotides to
make the continuous leading strand.
(a) Topoisomerase:- these enzymes participate in the overwinding or
underwinding of DNA.
(b) Helicases:- The main function of helicases is to unwinding
one's genes.
(d) Nucleases:- these enzymes are capable of cleaving the
phosphodiester bonds between monomers of nucleic acids.
(e) Primase:- it is a type of RNA polymerase.
-it catalyzes the synthesis of a short RNA segment called a primer
complementary to a ssDNA template.
