Problem Set # 9 1. The diagram below shows the transcribed region of a typical eukaryotic protein-coding gene. What is the size (in nucleotides) of the mature mRNAs derived from this gene [assume a poly(A) tail of 200 nucleotides]- a. If both introns are spliced out? b. If only intron 2 is spliced out? 2 . Match the terms on the left with one of the descriptions on the right . ______ 1. Sigma factor a. Intervening sequences found in most eukaryotic genes. ______ 2. Poly (A) tail b. The RNA polymerase in the nucleus that catalyzes the synthesis of all rRNAs except for the small 5S rRNA. ______ 3. Exons c. The subunit of bacterial RNA polymerase that is responsible for the initiation of transcription at promoters. ______ 4. RNA polymerase III d. The population of primary transcripts in the nucleus of an eukaryotic cell. ______ 5. Introns e. The RNA polymerase in the nucleus that catalyzes the synthesis of transfer RNAs, 5S rRNA and small nuclear RNAs ______ 6. RNA Polymerase II f. A polyadenylic acid tract 20 to 200 nucleotides long that is
