Biochemistry - Part 3

You have obtained a sample of DNA, and you transcribe mRNA from this DNA and purify it. You then separate the two strand

nucleic acid structure and recombination analysis shows hairpin formation, Holliday junction resolution and translation control ensure fidelity. Consequently Strand 1 emerges as the valid choice since it matches molecular mechanisms, aligning with established principles in molecular biology literature.

Ref: Watson et al., Molecular Biology of the Gene, 7th Edition, Chapter 9, Transcription and RNA Processing, describes RNA hairpin formation, secondary structures and regulatory mechanisms controlling gene expression.

Transcription Basics

The strand having same sequence as RNA (except T/U) is called

Nomenclature for DNA strands relative to transcription distinguishes informational equivalence. Template strand directly read by polymerase and complementary to RNA. Opposite strand contains sequence identical to RNA product except thymine replaces uracil, hence called coding, sense, or non-template strand. When gene sequence deposited in databases, coding strand displayed in 5' to 3' orientation matching mRNA for convenience interpreting codons. This strand does not contact catalytic center. Recognition that RNA equals coding sequence simplifies annotation of promoters, open reading frames, a
