Question

The thread like structure which appears inside the nucleus is

Spindle fibers
Centrioles
Asters

hint Hint:

Chromosomes

The correct answer is: Chromosomes

The thread like structure which appears inside the nucleus is chromosomes.

Each chromosome is composed of DNA and proteins.

So, the correct option is d.

From the smallest to the largest, how genetic information would be organized?

Nucleotides:

¶Nucleotides are the monomeric building blocks of nucleic acid polymers, deoxyribonucleic acid, and ribonucleic acid. Nucleotides follow genes.
¶

Genes:

¶Genes are DNA regions that instruct cells on making proteins, and they are the fundamental physical and functional units of heredity. Because chromosomes contain genes, their organization is similar to that of chromosomes.
¶

Chromosomes:

¶Chromosomes are threadlike structures inside the nucleus of animal and plant cells, made up of protein and a single molecule of DNA.
¶

Cells:

¶Cells are the basic building blocks; the human body consists of Trillions of cells. They provide structural support to the body, absorb nutrition from food, convert those nutrients into energy, and perform specialized functions. In addition, cells can replicate themselves and contain the body's genetic material.
¶

Nucleus:

¶The command center of the cell is the nucleus, sending instructions to the cell to grow, mature, divide, or die. It also contains the cell's hereditary material, DNA (deoxyribonucleic acid). The nuclear envelope protects the DNA and separates the nucleus from the surrounding cell.
