What does DNA and DNA? mean
What does a question mark indicate at the end of the family.
Thank you in advance,

The "DNA" class stands for DNA Tranposon -- a cut and paste type of interspersed repeats.

Yah but what does 'DNA?' mean
what is the difference between 'DNA' and 'DNA?'

Sorry, I didn't see the "?" in your original question. The "?" following either a class for subclass is an indication that the curator is not confident in the call of the class or subclass. As we learn more about the element in question the classification is either changed or the "?" designation is removed.
