In eukaryotic cells, in what form is DNA primarily found during interphase?
A
As free, naked DNA molecules floating in the nucleoplasm without associated proteins
B
As diffuse chromatin (DNA wrapped around histones and not fully condensed into visible chromosomes)
C
As RNA transcripts packaged into nucleosomes
D
As fully condensed metaphase chromosomes aligned at the metaphase plate
Guida verificata passo dopo passo1
Recall the cell cycle phases, focusing on interphase, which is the period when the cell is not dividing but preparing for division.
Understand that DNA in eukaryotic cells is associated with proteins called histones, forming a complex called chromatin.
During interphase, DNA is not fully condensed into visible chromosomes but exists in a less compact form called diffuse chromatin.
Diffuse chromatin consists of DNA wrapped around histones, allowing access for transcription and replication processes.
Therefore, the DNA during interphase is primarily found as diffuse chromatin, not as free DNA, RNA transcripts, or fully condensed metaphase chromosomes.
