Your Performance  

1.

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
 

2.

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 :

  terminator

  exon

  telomere

  promotor

  Half-n-half Clue
 

3.

An RNA molecule that can catalyze either its own cleavage (self-splicing) or the cleavage of other RNA molecules is :

  A ribozyme

  A chaperone enzyme.

  A spliceosome

  An inducer

  Half-n-half Clue
 

4.

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
 

5.

A collection of genes including one which acts as a switch that governs the expression of the structural genes in the collection is called :

  An Operon

  lac operon

  A regulon

  Does everything have to have a name ? ? ! !

  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.

A segment of DNA that includes regions preceding and following the coding DNA ( introns as well as exons ) is called :

  retroposon

  cistron

  operon

  Half-n-half Clue
