Which statement regarding the 'coding strand' of DNA is correct?

  1. It is used as the direct template by RNA polymerase
  2. Its sequence matches the mRNA, with U in place of T
  3. It is read by RNA polymerase in the 3' to 5' direction
  4. It is also called the antisense or template strand
Show answer and explanation

Correct answer: Its sequence matches the mRNA, with U in place of T

The coding (sense) strand is complementary to the template strand. Because RNA is synthesized complementary to the template, its sequence matches the coding strand — with uracil substituted for thymine. The coding strand is not directly used by RNA polymerase.
