Textbook Question

Chapter 17, Problem 1MCQ

A prokaryotic cell is one that

a. lacks DNA.
b. has membrane-bounded organelles.
c. lacks a nucleus.
d. lacks a plasma membrane.

Expert Solution & Answer

Summary Introduction

Introduction:

A prokaryotic cell is a primitive cell with unbound organelles and genetic material. It makes up the two of the three domains which are Bacteria and Archaea. They have less organelles and lesser specializations.

Answer to Problem 1MCQ

Correct answer:

A prokaryotic cell lacks the nucleus. Therefore, option c. is correct.

Explanation of Solution

Reason for the correct statement:

The prokaryotes have a single DNA strand, lacking histones and even a membrane. The DNA is just present in the cytoplasm like other organelles. It is called a nucleoid. The proper double membrane bound nucleus found in eukaryotes is missing in prokaryotes.

Option c. is given as “lacks a nucleus”.

As, “a prokaryotic cell is one that lacks a nucleus”, is the right answer.

Hence, the option c. is correct.

Reasons for the incorrect statements:

Option a. is given as “lacks DNA”.

DNA is the carrier of all the hereditary information. It is present in all the organisms. So, it is a wrong answer.

Option b. is given as “has membrane-bounded organelles”.

A prokaryotic cell does not have any membrane bound organelles. So, it is a wrong answer.

Option d. is given as “lacks a plasma membrane”.

Plasma membrane encloses the cytoplasm of a cell. It is present in all the cells. So, it is a wrong answer.

Hence, options a., b. and d. are incorrect.

Conclusion

One very distinctive feature between eukaryotes and prokaryotes is the presence and absence of nucleus, respectively.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
