1. Sections of DNA within a gene that do not encode part of the protein that the gene produces are called :   intein   Transposons   Introns   Exons   Hint Half-n-half Clue   2. A gene that encodes RNA that functions without being translated into a protein is called :   An RNA gene   AN Oncogene   A quiet gene   A pseudogene   Half-n-half Clue   3. 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   4. 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   5. Genes that are expressed at all times and under all conditions of growth are called :   antibody genes   regulatable genes   constitutive genes   chimeric genes   Half-n-half Clue   6. An RNA molecule that can catalyze either its own cleavage (self-splicing) or the cleavage of other RNA molecules is :   A spliceosome   A chaperone enzyme.   An inducer   A ribozyme   Half-n-half Clue   7. Due to the presence of Introns and Exons, in Eukaryotes the splicing process of pre-mRNA can lead to different ripe mRNA molecules and therefore to different proteins. This phenomenon is called :   gene splicing   alternative splicing   exonic splicing   intronic splicing   Half-n-half Clue
