LIFESCI 3 Study Guide - Midterm Guide: 5S Ribosomal Rna, Ribosomal Rna, Nucleoside Triphosphate
Document Summary
: a class of rna molecules, each of which is complementary to one strand of dna, that carry the genetic message from the chromosome to the ribosomes. Transfer rna (trna): combines covalently with a specific amino acid for use in protein synthesis. ribosomes. One of the three eukaryotic rna polymerases; pol iii transcribes genes encoding large rrna precursors. transcribes most of the protein-coding genes. transcribes genes encoding trnas, some snrnas, 5s ribosomal rna, and other small functional rnas. Initiation: polymerase binds to the origin of replication. (2) the first of three stages in the synthesis of rna, in which the rna polymerase binds to the promoter sequence on the dna. (3) The first of three stages in the synthesis of a protein, in which the ribosome binds to the mrna and initiator aminoacyl-trna. The strand of a double-stranded dna that has the same sequence as the.
