🤓 Based on our data, we think this question is relevant for Professor Brace's class at USF.

Solution: Which of the following statements about DNA and RNA is FALSE?a. DNA forms a double-stranded helical structure that contains base pairs whereas RNA is single stranded and does not form base pairs or adopt a double helical conformation.b. DNA and RNA are both synthesized in the 5' to 3' direction.c. DNA serves as the template for the synthesis of DNA during DNA replication and for RNA during transcription.d. The energy for both DNA and RNA synthesis comes from cleavage of phosphoanhydride bonds in the deoxynucleotide or nucleotide building blocks.e. DNA contains the bases A, G, C and T, whereas RNA contains the bases A, G, C and U.
