The "X" shaped chromosomal hereditary material can be packaged in this organelle in eukaryotic cells but not in prokaryotic cells.This organelle is the:
A)mitochondria.
B)chloroplast.
C)nucleoid.
D)nucleus.
E)ribosomes.

Question

Quizplus · Accepted Answer

The X-shaped chromosomal hereditary material is the DNA molecule, which is packaged into chromosomes in eukaryotic cells. This packaging occurs within the nucleus, which is unique to eukaryotic cells and not present in prokaryotic cells such as bacteria. Therefore, the correct answer is D) nucleus. Option A, mitochondria, and option B, chloroplasts, both contain their own circular DNA molecules but do not package the larger chromosomal DNA. Option C, the nucleoid, is the region in prokaryotic cells where the DNA is found but lacks a defined membrane-bound structure like the nucleus. Option E, ribosomes, are responsible for protein synthesis and do not play a role in chromosomal packaging.
