  retroposon

  transposon

  cistron

  operon

  Half-n-half Clue
 

2.

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

  Half-n-half Clue
 

3.

The series of three consecutive mRNA bases coding for one specific amino acid in a protein is called a :

  codon

  intron

  transposon

  exon

  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.

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
 

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

  terminator

  promotor

  telomere

  Half-n-half Clue
 

7.
