The term THEY MAY GET SPLICED can be solved by the crossword solution GENES, which are the basic physical and functional units of heredity. Genes are made up of DNA and act as instructions to make molecules called proteins, which then do most of the work in cells. Genes can be spliced, which is a process that involves cutting and joining together pieces of DNA from different sources. Splicing can be used to create new combinations of genes, which can lead to new traits or characteristics.
