Why does RNA contain uracil and DNA contain thymine? Choose the one BEST answer. correct answers Spontaneous cytosine deamination generates uracil, which base pairs with adenine during replication, 
and thereby converts a C-G base pair to a T-A base pair. 
 
RNA is typically more susceptible to backbone 
hydrolysis than DNA because of a chemical property. correct answers The presence of a 2' OH group 
 
Choose 3 reasons why RNA is a dynamic
