MULTIPLECHOICE 1k




1. Astudent isobservinga cellunder the microscope. It is observed to have supercoiled DNA with
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




1k histones. Which of the following would also be observed by the student?
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




a. Asingle circular chromosome 1k 1k 1k




b. A nucleus 1k




c. Free-floatingnuclear material 1k 1k




d. No organelles 1k




ANS: B 1k




The celldescribed isa eukaryotic cell, so it has histones and a supercoiled DNAwithin its nucleus;
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




1k thus, the nucleus should be observed.
1k 1k 1k 1k 1k




Asingle circular chromosome ischaracteristic ofprokaryotic cells, whichdo not have histones.
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




Free-floating nuclear materialdescribesa prokaryotic cell,whichwouldnot havea distinct nucleus.
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




Eukaryoticcells have membraneboundedcellular componentscalledorganelles. No organelles describes
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




1k a prokaryotic cell.

2. Anurse is instructing thestaff about cellular functions. Whichcellular function isthenurse
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




1k describing when an isolated cell absorbs oxygen and uses it to transform nutrients to energy?
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




a. Metabolic absorption 1k




b. Communication
c. Secretion
d. Respiration

,ANS: D 1k




The abilityof the cellto absorb oxygen refers to the cells function of respiration.
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




The abilityof the cell to function within a societyof cells refers to its function of communication.
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




The abilityof the cellto take in nutrients refers to the cells function of metabolic absorption.
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




The abilityofthe cellto synthesize new substances and secrete these elsewhere refers tothe cells function
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




1k of secretion.

3. Aeukaryotic cell is undergoing DNAreplication. Inwhich region ofthe cellwould most of the
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




1k genetic information be contained? 1k 1k 1k




a. Mitochondria
b. Ribosome
c. Nucleolus
d. Nucleus


ANS: C 1k




The regionofthe cellthat contains genetic material, including a large amount ofribonucleic acid,
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




1k most of the DNA, and DNA-binding proteins, is the nucleolus.
1k 1k 1k 1k 1k 1k 1k 1k 1k




The mitochondria isthe siteofcellular respiration.
1k 1k 1k 1k 1k 1k 1k




Theribosomes are involved in manufacturing ofproteins withinthe cell.
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




Thenucleus contains the nucleolus, and it isthe nucleolus that contains genetic material.

4. The fluid mosaic modelforbiologic membranes describes membrane behavior. According to this
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




1k model, which of the following float singly or as aggregates in the fluid lipid bilayer?
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




a. Peripheralmembrane proteins 1k 1k




b. Integral membrane proteins 1k 1k

, c. Glycoproteins
d. Cell adhesion molecules 1k 1k




ANS: B 1k




Integralmembrane proteins float freely inthe fluid lipid bilayer.
1k 1k 1k 1k 1k 1k 1k 1k 1k




Peripheralmembraneproteins arenot embedded in the layer, but resideat thesurface. Glycoproteins
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k




1k act as cell surface markers.
1k 1k 1k 1k




Celladhesion molecules are onthe outside ofthe membrane and allow cells to hooktogether.
1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k 1k
