Multiple Choice
In the context of eukaryotic chromosome structure, which statement about chromatin is correct?
A
Chromatin is DNA packaged with proteins (primarily histones) to form the material of eukaryotic chromosomes.
B
Chromatin is naked DNA with no associated proteins.
C
Chromatin is a membrane-bound organelle that stores DNA in eukaryotic cells.
D
Chromatin is the RNA-protein complex that carries out translation at ribosomes.
Verified step by step guidance1
Understand the definition of chromatin in eukaryotic cells: Chromatin is the complex of DNA and proteins found in the nucleus that packages and organizes DNA into chromosomes.
Recall that the primary proteins involved in chromatin structure are histones, which help in winding DNA into a compact form.
Recognize that chromatin is not naked DNA; DNA without proteins is not stable or efficiently organized within the nucleus.
Eliminate incorrect options by understanding that chromatin is not a membrane-bound organelle, nor is it an RNA-protein complex involved in translation (which describes ribosomes).
Conclude that the correct statement is that chromatin is DNA packaged with proteins (primarily histones) to form the material of eukaryotic chromosomes.
