RNA is different from DNA in several ways. Whereas DNA contains the sugar (1) ________________________, RNA contains the sugar (2) ________________________. In addition, RNA is made using the nitrogen-containing base (3) ________________________, while DNA contains the base (4) ________________________. Both RNA and DNA, however, contain (5) ________________________ groups. Unlike DNA, RNA exists in three different types. One type, known as (6) ________________________, carries the genetic information from the (7) ________________________ to the (8) ________________________ where the proteins are synthesized. A second type of RNA, called (9) ________________________ transports the amino acids to the (10) ________________________. These structures are made of proteins. The third type of RNA is called (11) ________________________. All three types of RNA are made from DNA in a process called (12) ________________________. Just as the DNA does in replication, the two strands of the (13) ________________________ separate. Then DNA makes a strand of RNA that is (14) ________________________ to the base sequence of the DNA. Therefore, the nitrogen-containing base (15) ________________________ will pair with a cytosine base in DNA, while (16) ________________________ will pair with a thymine base in DNA.
