1.

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

  cistron

  retroposon

  operon

  transposon

  Half-n-half Clue
 

2.

Sections of DNA within a gene that do not encode part of the protein that the gene produces are called :

  Transposons

  Exons

  intein

  Introns

  Half-n-half Clue
 

3.

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
 

4.

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 selfish gene
