1. A RNA transcript (whose base sequence is complementary to that of the mRNA of a gene) that can inhibit the expression of a gene by forming a duplex with the mRNA strand is called :   antisense RNA   tRNA   dsRNA   rRNA   Hint Half-n-half Clue   2. The series of three consecutive mRNA bases coding for one specific amino acid in a protein is called a :   exon   codon   intron   transposon   Half-n-half Clue   3. 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 :   a Shine-Dalgarno sequence   trailer   the poly-A-tail   cap   Half-n-half Clue   4. 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   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. 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   7. 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
