Practice question
Question
All the DNA strands of a cell containing 4 chromosomes are labelled. After one division how many chromosomes in the daughter cell will have labelled DNA?
Explanation
Mechanistically, nucleic acid structure and recombination involves hairpin formation, Holliday junction resolution and translation control ensure fidelity. This validates 4 because it matches molecular mechanisms of gene expression, a pattern repeatedly demonstrated in molecular biology research.
