Which of the following will not affect eukaryotic cells?
a. Inhibition of the mitotic spindle
b. Binding with sterols
c. Binding to 80S ribosomes
d. Binding to DNA
e. All of the above will affect them

Guida verificata passo dopo passo

Step 1: Understand the context of the question, which is about factors that affect eukaryotic cells. Each option describes a different mechanism that could interfere with cellular functions.

Step 2: Analyze option (a) - inhibition of the mitotic spindle. The mitotic spindle is essential for chromosome separation during mitosis in eukaryotic cells, so inhibiting it will affect eukaryotic cells.

Step 3: Analyze option (b) - binding with sterols. Sterols, such as cholesterol, are components of eukaryotic cell membranes. Binding with sterols can disrupt membrane integrity, thus affecting eukaryotic cells.

Step 4: Analyze option (c) - binding to 80S ribosomes. Eukaryotic ribosomes are 80S (composed of 60S and 40S subunits). Binding to 80S ribosomes would interfere with protein synthesis in eukaryotic cells.

Step 5: Analyze option (d) - binding to DNA. DNA is present in eukaryotic cells, and binding to DNA can affect replication and transcription, thus impacting eukaryotic cells. After evaluating all options, determine which one does not affect eukaryotic cells.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Eukaryotic Cell Structure and Function

Eukaryotic cells have distinct organelles such as a nucleus, mitochondria, and a cytoskeleton including the mitotic spindle, which is essential for chromosome separation during cell division. Understanding these structures helps explain how certain agents affect cell processes.

Sterols in Cell Membranes

Sterols, like cholesterol, are important components of eukaryotic cell membranes, contributing to membrane fluidity and integrity. Agents that bind sterols can disrupt membrane function, affecting eukaryotic cells specifically.

Differences Between Prokaryotic and Eukaryotic Ribosomes

Eukaryotic ribosomes are 80S, composed of 60S and 40S subunits, while prokaryotic ribosomes are 70S. Some drugs target 70S ribosomes specifically, so binding to 80S ribosomes affects eukaryotic cells differently, which is crucial for understanding selective toxicity.
