What is the complementary RNA sequence for the following segment of DNA? ACC TAG CGA Question 6 options: ACC TAG CGA UGG AUC GCU
RUDIKE [14]

RNA is a single-stranded molecule, which is made up of similar composition as DNA. RNA differs from DNA in the nitrogenous base as it has uracil in place of thymine.

<h3>What is the complementary RNA sequence?</h3>

  • A complementary sequence refers to the copy of the strand or template strand of the RNA. The complementary strand will be the copy of the original strand.

  • In the complementary base pairing, guanine will be complementary to cytosine and adenine to uracil.

  • In the given sequence of RNA, ACC TAG CGA, the complementary sequence formed will be UGG AUC GCU.

Thus, the complementary sequence will be UGG AUC GCU.
