1. Sections of DNA within a gene that do not encode part of the protein that the gene produces are called :   intein   Exons   Transposons   Introns   Hint Half-n-half Clue   2. An RNA molecule that can catalyze either its own cleavage (self-splicing) or the cleavage of other RNA molecules is :   A chaperone enzyme.   A spliceosome   An inducer   A ribozyme   Half-n-half Clue   3. The base sequence of the RNA strand transcribed from a DNA strand of the sequence T-G-C-A-G-C-A-C-A is :   A-C-G-U-C-G-U-G-U   A-C-G-U-C-G-U-G-U   U-G-C-A-G-C-A-C-A   G-U-A-C-U-A-C-A-C   Half-n-half Clue   4. A collection of genes including one which acts as a switch that governs the expression of the structural genes in the collection is called :   An Operon   lac operon   A regulon   Does everything have to have a name ? ? ! !   Half-n-half Clue   5. The process by which messenger RNA is synthesized by complementary base pairing of ribonucleotides with deoxyribonucleotides to match a section of DNA (a gene) is called :   Translation   Replication   Transcription   I have no idea ! !   Half-n-half Clue   6. A guanine triphosphate nucleotide that binds to the 5' end of the mRNA thus increasing the stability of the synthesized RNA and enhancing translation efficiency is called a :   Cap   trailer   poly-A-tail   leader   Half-n-half Clue   7. A segment of DNA that includes regions preceding and following the coding DNA ( introns as well as exons ) is called :   operon   cistron   transposon   retroposon   Half-n-half Clue
