Question

Name the part of the cell that contains a network of chromatin fibers.
A. nucleus
B. DNA
C. Mitochondria
D. Cell membrane

Answer 1

Hint: The nucleosome is composed of an octameric center of histone proteins around which the DNA double helix is wrapped. Notwithstanding irregularities in the positioning of nucleosomes along with DNA, nucleosomes are typically packed collectively into quasi-regular arrays to form a 30-nm fiber.

Complete answer:
Deoxyribonucleic acid (DNA) encodes the genetic commands, which commonly are used in the improvement and functioning of all residing organisms. every DNA strand is fabricated from a genuinely basic unit of one nitrogenous base + phosphate institution + sugar molecule in an especially massive manner. The mobile membrane is the outer masking of the mobile, which protects the cellular, so deoxyribonucleic acid (DNA) encodes the genetic commands, which are used in the improvement and functioning of all dwelling organisms. Every DNA strand is fabricated from a sort of basic unit of 1 nitrogenous base + phosphate group + sugar molecule, which in particular in all fairness is significant. Each DNA strand for the maximum part is manufactured from a normally basic unit of one nitrogenous base + phosphate institution + sugar molecule subtly. The nucleus of the mobile contains the majority of the mobile's genetic cloth, i.e., DNA inside the shape of DNA-protein complicated, referred to as chromatin, so the nucleus of the mobile contains the majority of the mobile's genetic cloth, i.e DNA inside the form of DNA-protein complex, known as chromatin, helps in all intents and functions in the most important way.

So, the correct answer is option A.

Note:
A couple of histones wrap right into a 30-nanometer fiber consisting of nucleosome arrays of their most fairly compact shape, which indicates that DNA wraps around histone proteins, forming nucleosomes and the virtually so-called "beads on a string" structure, demonstrating that during a type of big manner.
