Since Watson and Crick described the structure of DNA in 1953,which of the following statements might best explain why the function of small RNAs is still being explained?
A)As RNAs have evolved since that time,they have taken on new functions.
B)Watson and Crick described DNA but did not predict any function for RNA.
C)The functions of small RNAs could not be approached until the entire human genome was sequenced.
D)Changes in technology as well as our ability to determine how much of the DNA is expressed have now made this possible.

Changes in technology, such as RNA sequencing and genome-wide analysis, have allowed us to better understand the functions of small RNAs. Additionally, our ability to determine gene expression patterns has aided in discovering the regulatory roles of small RNAs. While small RNAs have evolved since the discovery of DNA's structure, this alone does not fully explain why their functions are still being explained. Watson and Crick's focus was on DNA, but they did suggest some possible functions for RNA, such as messenger RNA. The sequencing of the human genome was a significant milestone, but it alone did not allow for the study of small RNAs; further advancements were necessary.
