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   inducer   Operator   Repressors   Hint Half-n-half Clue   2. 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   3. The sequence of bases located prior to the gene (along the DNA strand), to which a complex of RNA polymerase and sigma factors attaches itself to initiate transcription is called :   exon   telomere   promotor   terminator   Half-n-half Clue   4. 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   5. A G-C-rich stretch of nucleotides, followed by an A-T-rich stretch of nucleotides is the signal for :   Rho independent termination   Rho dependent termination   Initiation   transcription   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   poly-A-tail   trailer   leader   Half-n-half Clue   7. Genes that are expressed at all times and under all conditions of growth are called :   constitutive genes   antibody genes   regulatable genes   chimeric genes   Half-n-half Clue
