Document Summary

Process of releasing info contained in a dna sequence. Molecules of rna are assembled on dna templates in nucleus. Genes are transcribe into 3 rnas: ribosomal: nucleic acid chain combined with protein to form ribosomes, messenger: carries protein- building instructions, delivered to ribosomes, transfer: rna molecules serves as an adapter b/w nucleotide sequence of nucleic acids. Rna polymerase synthesizes an rna transcript using one strand of dna as template. Amino acids are assembled into a chain, the primary structure of a protein. Initiation: trna starts transcription loaded onto ribosome subunit: elongation: polypeptide chains forms as the mrna strand passes between ribosome subunits, termination: stop codon in the mrna, enzymes detach and new chain start from ribosomes. Region of a dna molecule containing a sequence of basis that is transcribed into a functional product: regulatory region: controls initiation of transcription, coding region: bases read into functional molecules, termination region: stops transcription.
