NCBI Genome Database – Comparing Human and Chimp DNA

Hemoglobin ncbi image

 Learning Objectives:  to search for DNA sequences of the NCBI Database – the same database real scientists use for studying genes; to compare and contrast the human and chimpanzee gene sequence for the beta subunit of the hemoglobin gene; to generate the amino acid sequence of one exon of the HBB gene; to identify exons and introns in the sequence; to analyze the differences between the sequences and conclude why there are more differences in introns than in exons.

Key concepts: DNA structure, complementary base pairing, mRNa, transcription & translation, exon & intron, hemoglobin, evolution & natural selection.
