1. Proteins that bind between the promotor region and the section of the gene which is transcribed thus blocking transcription (preventing gene expression) are called :   Activators   Repressors   inducer   Operator   Hint Half-n-half Clue   2. 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   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 segment of DNA that includes regions preceding and following the coding DNA ( introns as well as exons ) is called :   transposon   cistron   operon   retroposon   Half-n-half Clue   5. Sections of DNA within a gene that do not encode part of the protein that the gene produces are called :   intein   Transposons   Introns   Exons   Half-n-half Clue   6. 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   7. The series of three consecutive mRNA bases coding for one specific amino acid in a protein is called a :   transposon   exon   codon   intron   Half-n-half Clue
