Which structural characteristic is seen in RNA but not in DNA?

Question

double strands

a single strand

chains of nucleotides

a helical shape

Answer 1

All of the options are true of DNA, except the single strand! DNA is a double strand helix made of nucleotides that bond in specific pairs! RNA is a single strand of DNA (thymine being replaced by uracil) used as a template for creating proteins from the sequence of amino acids in the single strand.
