DNA Science Reading Passage
This eight-page PDF contains one lesson: a two-page DNA reading, ten multiple-choice questions, six written-response questions, a six-word spelling activity and two answer pages.
Use the reading to discuss DNA structure, base pairs and replication, then have students support answers with passage details. The multiple-choice key quotes supporting text, while the additional questions have model responses. Designed for Grade 5–6 science reading with support as needed.

Teaching tips & learning objectives
Learning objectives
Explain how DNA's base-pair code (A-T, G-C) functions as an instruction manual for a cell
Describe how DNA replicates and compare how the passage describes DNA in identical and fraternal twins
Use domain-specific science vocabulary (organism, nucleus, chromosome, geneticist) correctly
Teaching tips
Read the passage's spiral-staircase and instruction-manual analogies aloud before the questions, since several multiple-choice items (1, 4, 5, 6) test recall of those exact comparisons.
Use the answer key's quoted supporting sentences as a model for how to cite evidence from a text, using the multiple-choice explanations that quote the passage.
Assign the spelling section after the reading and question sections, since its six words (organism, nucleus, chromosome, geneticist, compounds, reproduction) are the same vocabulary used throughout the passage and answer key.
Skills covered
Reading informational science text — comprehending a two-page explanatory passage on DNA structure and function.
Citing textual evidence — the answer key models pointing to the exact passage sentence that supports each answer.
Domain-specific vocabulary — spelling and defining six genetics terms drawn directly from the passage.
Good to know
Questions teachers ask about this resource
Are the six open-response questions given model answers too, not just the multiple-choice ones?
Yes — each of the six 'Additional Questions' has a full written model answer, in addition to explanations for all 10 multiple-choice questions.
What clues are supplied for spelling?
Six definitions and two or three given letters within each word help students complete organism, nucleus, chromosome, geneticist, compounds and reproduction.
