Single-stranded genetic stuff crossword clue
30 Across · WSJ Crossword, October 27, 2026 · 3 letters
Explanation
The answer to “Single-stranded genetic stuff” is RNA. It appears as 30 Across in the Wall Street Journal crossword of October 27, 2026, a Tuesday puzzle titled “Set a Side” by Christopher Youngs, and it fills 3 squares running left to right from row 6, column 13 of the 15×15 grid.
The clue is a straightforward definition, so the answer is a direct synonym or a factual match for the words as written. The entry begins with R and ends with A, and contains 1 vowel and 2 consonants. If you are working from the crossings, two or three confirmed letters from the Down entries should be enough to lock it in. Tuesday puzzles stay approachable with light wordplay, so expect the rest of this grid to be pitched at the same level.
