Document Summary
From gene to protein: overview, the flow of genetic information (page 325, gene expression- the process by which dna directs the synthesis of proteins (or sometimes just rnas) Bio 191: triplets of nucleotide bases are the smallest units of uniform length that can code for all the amino acids (three consecutive nucleotide bases speci es an amino acid. Bio 191: synthesis of an rna transcript, start point- the nucleotide where rna synthesis actually begins, transcription factors- a collection of proteins that mediate the binding of. In bacteria, the small subunit can bind these two in either order; it binds the mrna at a speci c rna sequence, just upstream of the start codon, aug. Proteins called initiation factors, are required to bind all the translation components together. Hydrolysis of gtp provides the energy for the assembly. Uag, uaa, uga code not for amino acids but to end translation.
