Document Summary
Where does the energy come from: triphosphate. Central dogma: flow of information within a cell, the flow is largely in one direction. Transcription involves making ___from dna: rna. Translation involves making ____ from _____: proteins, rna. Rna processing: cappi(cid:374)g: o(cid:374) the 5" e(cid:374)d, poly- a tail: o(cid:374) the 3" e(cid:374)d, editing: cut up and changed. The human dystrophin gene contains 2. 4 million base pairs with 79 exons, while the final (mature) mrna transcribed from this gene id 14,000 base pairs. What percentage of the dna in this gene actually codes for the protein: about 0. 5% Translation: occurs in the cytoplasm at a ribosome, mrna to polypeptide (nucleotide sequence to amino acid sequence) 3 nucleotides per 1 amino acid: triplets (codons, degenerate code: multiple triplets that code for 1 amino acid. The mrna sequence gcc codes for the amino acid? (given a table: ala. Which codon codes for the amino acid arginine (arg): more than one.
