1.

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
 

2.

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
 

3.

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
 

4.

The lac repressor protein binds to the operator region...

  in the absence of lactose

  in the presence of lactose

  in the presence of cAMP

  in the absence of glucose

  Half-n-half Clue
 

5.

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
 

6.

A base sequence that is part of the DNA of an organism and appears to have once coded a gene product, such as a protein or transcription factor but no longer does so is called :

  A jumping gene

  A pseudogene

  A selfish gene

  An Oncogene

  Half-n-half Clue
 

7.

Proteins that bind between the promotor region and the section of the gene which is transcribed thus blocking transcription (preventing gene expression) are called :

  Repressors

  Activators

  Operator

  inducer

  Half-n-half Clue
