Genetics Lecture Final

charges a tRNA with its appropriate amino acid

transcribes rDNA to produce the 45S rRNA precursor

transcribes protein encoding genes

transcribes tRNA, 5S rRNA, and some snRNA genes

simultaneously binds to the sequences TTGACA and TATAAT

Complex of proteins that recognizes the sequence TATAA in eukaryotes

basal transcription factor required for transcription of tRNA

basal transcription factor for RNA Pol I

this protein is required for transcription initiation by all 3 eukaryotic RNA polymerases

binds to prokaryotic mRNAs to cause transcription termination

the ribozyme activity of the large subunit of the rRNAs

recognizes the sequence UAA

causes aminoacylated tRNAs to bind to the ribosome

factor responsible for translocation of the ribosome

factor that assembles tRNAi, with the small ribosomal subunit-mRNA complex

factor that recognizes the cap of eukaryotic mRNAs

helps to dissociate the other elongation factors, which allows the large ribosomal subunit to bind

is the 1st molecules to base pairs at the 5 splice sites of introns of eukaryotic pre-mRNAs

binds to the branch point in introns of eukaryotic pre-mRNAs

base pairs at the 3 splice sites of introns of eukaryotic pre-mRNAs

this enzyme modifies the 5 end of the mRNAs

this enzyme modifies the 3 end of mRNAs
