Sarah0000 Posted October 17, 2018 Share Posted October 17, 2018 My first grader is writing about what he learned from a Magic School Bus episode. He's writing "DNA is the building blocks of life." He says Ms. Frizzle said it that way, not DNA are the building blocks and not DNA is the building block. I didn't watch the episode so I don't know what she said. Is there perhaps an exception for acronyms or maybe the show was wrong. What is grammatically correct? Quote Link to comment Share on other sites More sharing options...
Sarah0000 Posted October 18, 2018 Author Share Posted October 18, 2018 What's it suppose to be though? Should DNA be singular or plural? Quote Link to comment Share on other sites More sharing options...
Lori D. Posted October 18, 2018 Share Posted October 18, 2018 (edited) DNA stands for deoxyribonucleic acid -- a singular noun. So "is" is correct, but the plural of "blocks" is incorrect as the sentence is currently constructed. For a grammatically correct sentence, either: "DNA is a building block of life."or "DNA is one of the building blocks of life." Edited October 18, 2018 by Lori D.
