Document Summary
14. 1 the connection b/w dna, rna and protein. 14. 1a genes specify either protein of rna products. Ulkaptonuria: disease where one"s urine turns black in air. People with this disease lack an enzyme that brks down a key chemical that is exerted and turns black in urine; happens as a result of an alternation of a gene that encodes for this enzyme. Neurospora crassa: haploid fungus with simple notorious needs. When exposed to x ray, the mutant strains wouldn"t grow without aa and vitamins. Showed the direct relationship b/w genes and enzymes, which they put forward as the one gene- one enzyme hypothesis, which was later restated, since some proteins made up of many polypeptides. 14. 1b the pathway from gene to polypeptide involves transcription and translation. Transcription: info from dna is made into complementary rna. Translation: use of info in rna to assemble aa into a polypeptide.
