Document Summary
Proteins: proteins are the active players in most cell processes. Involved in essentially all sub-cellular, cellular, and developmental functions in living organisms: major classes of proteins, enzymatic: catalysts in biochemical reactions (dna/rna polymerases, regulatory: control of gene expression, intercellular signaling (transcription factors, structural: cellular or organismal anatomy. Amino acids: amino acids are the building blocks of proteins http://www. johnkyrk. com/aminoacid. html. Translation: process of converting information stored in nucleic acid sequences into proteins, genetic code: the ribosomes read mrna sequences in 3-base codons. The template that is used to specify amino acid sequence ribosomes a complex of proteins and rrna molecules transfer rna (trna) Small (70-80 nucleotide) rna molecules that serve as adapters between codons in mrna and amino acids. The trna anticodon recognize the codon in mrna. The hydroxyl (3") end of each trna is linked to the carboxyl group of a specific amino acid. 4x4x4x4=64 different codons (don"t need to memorize the table)
