Dna is typically found as a double helix

WebUV radiation can make cytosine and thymine bases react with neighboring bases that are also Cs or Ts, forming bonds that distort the double helix and cause errors in DNA replication. The most common type of linkage, a thymine dimer , consists of two thymine bases that react with each other and become chemically linked 8 ^8 8 start superscript ... WebRNA often forms double-stranded structures. When RNA is double-stranded, the base-pairing rules are slightly modified when compared to those seen in DNA. Match the base on the left, with the base it would pair with on the right. If one of the bases isn't found in RNA, indicate that using the appropriate label on the right.
