Document Summary
Transcription: the synthesis of an rna from a dna template. Info encoded in the 4 deoxyribonucleotide of dna is rewritten/transcribed into similar language made up of 4 ribonucleotide letters of rna mrna: messenger rna code for protein. Allows the cell to separate information storage from info utilization. Translation: complex process of protein synthesis in the cytoplasm rrna: ribosomal rnas transcribed from 1 of the dna strands. Form the basic structure of the ribosome and catalyze protein synthesis eukaryotic cell contains millions of ribosomes. Majority (more than 80% of rna) is rrna. 4 types: large subunit 5s, 5. 8s, 28s small subunit 18s. 5rdna clusters trna: transfer rnas made up of 3 major class of rnas that is. Required to translate the info in the mrna nucleotide code into the aa. of a polypeptide. Central to protein synthesis as adapters between mrna and aa. Base-paired regions form double-stranded stems connected to single-stranded loops.
