Document Summary
Dna is the instructions (program) that tells the cell what to do. The study of metabolic defects provided evidence that genes lead to proteins. The relationship was first proposed by archibald garrod in 1909: suggested that some metabolic disorders were caused by a blocked pathway, inherited diseases were the result of the lack of an enzyme. A blockage in a pathway not only stops the production of something we need but is also may lead to the accumulation of something we don"t want. Step 1: dna to rna: process is called transcription, the synthesis of rna using dna as a template. The rna is complimentary to the dna: rna that is synthesized from a gene coding for a protein in called messenger rna (mrna) or a transcript. What"s the diff between dna and rna: dna, sugars= deoxyribose, nucleotides (bases) = g, a, c, t, rna, sugar= ribose, nucleotides= g, a, c, u.
