Which of the following enzymes ensures that the correct base of a deoxynucleotide for growing the chain is aligned with template chain?
DNA gyrases
DNA ligases
DNA polymerases
primases
A single (+) strand of DNA (base composition: A, 21%; G, 29%; C, 29%; T, 21%) isreplicated by DNA polymerase to yield a complementary (−) strand. The resultingduplex DNA is then used a template by RNA polymerase, which transcribes the (−)strand. Indicate the base composition of the RNA formed.
Okazaki fragments are found on the _____________ strand.
