Which of the following features is common to prokaryotic cells?
- a. a nucleus, featuring a nuclear envelope with pores
- b. mitochondria
- c. plasma membranes
- d. mitotic spindle
- e. none of the above
Introduction: Prokaryotic cells are primitive and most abundant types of cells present on the Earth. They differ in many features from the advanced eukaryotic cells found on the surface of the Earth.
Answer to Problem 1TY
Correct answer: Plasma membranes are the structures that are common to prokaryotic cells. Hence, the correct answer is option c.
Explanation of Solution
Reason for correct answer:
All type of cells possesses plasma or cell membranes. These membranes are made up of lipids and act as a protective barrier between the internal and external environment of the cell. So, plasma membranes are present in prokaryotic cells.
Option c. is given as “plasma membranes”.
The structure or feature that is common to prokaryotic cells is plasma membrane. Hence, the correct answer is option c.
Reasons for incorrect answer:
Option a. is given as, “a nucleus, featuring a nuclear envelope with pores”.
The prokaryotic cells do not possess a well-defined membrane bound nuclei, but it encompasses a nucleoid. Hence, option a. is incorrect.
Option b. is given as, “mitochondria”.
Mitochondria act as powerhouse for the eukaryotic cells. Prokaryotic cells do not contain mitochondria. Hence, option b. is incorrect.
Option d. is given as, “mitotic spindle”.
Mitotic spindles are collective web of fibers that are present in eukaryotic cells. These fibers are used during division of chromosomes. These structures are not present in the prokaryotic cells. Hence, option d. is incorrect.
Option e. is given as, “none of the above”.
Plasma membrane is common to prokaryotic cells and the correct option is answer c. Hence, option e. is incorrect.
Hence, the options a., b., d., and e. are incorrect.
The prokaryotic cells possess plasma membranes made up of lipids and proteins.

Assume each arrow represents a reaction catalyzed by a different enzyme. Using the principles of feedback inhibition, propose a regulatory scheme for this pathway that ensures an adequate supply of both AMP and GMP, and prevents the buildup of Intermediates A through G when supplies of both AMP and GMP are adequate.arrow_forwardQUESTION 27 Label the structures marked A, B, C and explain the role of structure A.
