1. 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   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. 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 :   alternative splicing   gene splicing   intronic splicing   exonic splicing   Half-n-half Clue   4. A series of 20 to 200 Adenine ribonucleotides that is added to the 3' end of the transcribed RNA molecule (pre-mRNA) that helps in the transportation of mRNA out of the nucleus is called :   trailer   a Shine-Dalgarno sequence   the poly-A-tail   cap   Half-n-half Clue   5. The switch of an operon is turned on if specific substance is not bound to the operator. This substance is called :   a repressor   a promoter   an operon   an activator   Half-n-half Clue   6. Proteins that bind between the promotor region and the section of the gene which is transcribed thus blocking transcription (preventing gene expression) are called :   Repressors   inducer   Activators   Operator   Half-n-half Clue   7. A G-C-rich stretch of nucleotides, followed by an A-T-rich stretch of nucleotides is the signal for :   Rho dependent termination   Initiation   Rho independent termination   transcription   Half-n-half Clue
