BIO153H5 Lecture Notes - Lecture 9: Kermode Bear, Archibald Garrod, Dnainfo.Com
Document Summary
Same in every way to a black bear, but white. The symptoms of an inherited disease= inability to make enzyme. Mendels principles of heredity apply to humans. Separated in vial with minimum survival materials, one was in excess and could determine if that amino acid allowed growth. One gene-one gene enzyme hypothesis= a gene dictates production of enzyme that allows growth, if missing, prevents function. But, some genes code for rna (not protein) Making a polypeptide using mrna sequence to amino acid site: ribosomes. Bacteria= dna not separated by nuclear membrane translation and transcription occur at same time. Eukaryotes= nuclear envelope separates transcription in nucleus translation in cytoplasm: pre- mrna= transcription of protein coding gene, primary transcript= initial rna transcript (both protein coding and non) One species can be made to produce characteristics of another: plant glowing from firefly dna. Codons triplets of nucleotides, not overlapping template strand= transcribed. Mrna, complementary base pairs, u instead of t.
