• 1. 
    Eukaryotic entities

  • in the presence of a cAMP molecule, it carries out protein synthesis
  • have only operons assisting in gene expression
  • transcription takes place in the nucleus and translation in the cytoplasm
  • transcription occurs in the cytoplasm and translation in nucleus
  • 2. 
    A genomic DNA possesses functioning units, a group of genes under the influence of promoters known as

  • genes
  • operons
  • anticodon
  • codon
  • 3. 
    All regulatory proteins possess a common DNA binding motif that is specific flexes in their protein chains permitting them to interlock with

  • the outside groove of DNA helix
  • the major groove of DNA helix
  • the minor groove of DNA helix
  • the inner groove of DNA helix
  • 4. 
    Regulatory proteins turn transcription off through binding to a site rapidly at the front of the promoter and many times even overlaps the promoter, this site is the

  • regulatory site
  • operator site
  • suppressor site
  • transcriptional control site
  • 5. 
    Seemingly, the vertebrate cells contain a protein which binds to clusters of 5-methylcytosine ensuring that the bound gene stays in the “off” position This regulation on the role of gene regulation is an outcome of

  • Methylation
  • Translation
  • Enhancer expression
  • operator suppression
  • 6. 
    The transcriptional gene control in eukaryotes is mediated by

  • metabolites that bind to the cis-acting elements
  • trans-acting factors failing to bind to cis-acting elements
  • trans-acting factors binding to cis-acting elements
  • repressor proteins that bind to operator sites
  • 7. 
    Basic tools of genetic regulation are the ability of some proteins to bind to specific

  • regulatory DNA sequences
  • regulatory RNA sequences
  • enzymes of cells
  • promoter portions of genes
  • 8. 
    In the regulation of gene expression, this is an incorrect statement

  • in the bacteria, it permits to replicate with no control
  • in the bacteria, it permits to adapt to changing environments
  • permits the maintenance of homeostasis in multicellular entities
  • permits the functioning of multicellular entities on the whole
  • 9. 
    There are these many histones in the core of a nucleosome

    In eukaryotes and bacteria, the most common form of regulation is

  • promoter control
  • translation control
  • repressor control
  • transcriptional control
