- SSC CPO 2025 T-1 Spelling
Fill in the blank with the correctly spelt word.
The DNA strands were separated through ________ methods.Answer & explanation
Answer: B) electrophoresis
Correct Answer: Option 2 — electrophoresis
'Electrophoresis' is the correct spelling: E-L-E-C-T-R-O-P-H-O-R-E-S-I-S. It is a laboratory technique used to separate DNA, RNA, or proteins based on their size using an electric field.
Why the others are wrong:
Option 1 — 'Electroforesis' omits the 'ph' ('phore' becomes 'fore'); incorrect.
Option 3 — 'Electrophorresis' doubles the 'r' incorrectly ('rr' instead of 'r').
Option 4 — 'Electrophoreses' is the plural form of electrophoresis; the sentence requires the singular noun as a technique/method. - SSC Steno 2026 T-1 Spelling
Fill in the blank with the correctly spelt word.
The DNA strands were separated through _______ methods.Answer & explanation
Answer: B) electrophoresis
Rule: scientific words built from Greek keep the Greek ph for the *f* sound and take the ending -sis in the singular.
Example: *photosynthesis*, *analysis*, *hypothesis* — each ends in -sis; the plural changes it to *-ses*.
electrophoresis = electro + phoresis (Greek *phorein*, to carry).
It is the technique that separates DNA or proteins by moving them through a gel with an electric current *(वैद्युत-कण-संचलन, विद्युत क्षेत्र द्वारा अणुओं को अलग करने की विधि)*.
Spell it: e-l-e-c-t-r-o-ph-o-r-e-sis.
Why the others are wrong.
• electroforesis — uses *f* for the Greek ph; the misspelling *(ग़लत वर्तनी)* drops the *ph*.
• electrophorresis — doubles the *r*; the word has a single r *(दोहरा r ग़ल
