While existing approaches to sequence RNA require its conversion to DNA followed by manipulations, researchers have now created a technique that can sequence it directly. This often results in a loss of the original sequence that needed studying. DNA found in every cell is the same but RNA varies depending on what kind of protein has to be expressed. So, understanding this functional output is essential to understand biology better. The new method would allow study of genes that express faulty proteins and lead to diseases such as Huntington’s and Alzheimer’s
