Chromosome Structure Quiz

What is the name for the fundamental unit of chromatin in the packaging of DNA within a human chromosome?

What is the name given to the structure that results from the packaging of DNA with core histones?

What is the name of the protein complex that interacts with a heterogeneous group of nonhistone proteins, which are involved in establishing a proper spatial behavior and appropriate gene expression?

What is the name of the histone core structure that is organized around a segment of DNA, which is approximately 140 base pairs (bp) in length?

What is the name of the structure formed by the coiling of nucleosome fibers?

What is the name of the complex of DNA, which is further condensed beyond the solenoid level, resulting in a structure that is nearly 100 times shorter than the original DNA chain?

Chromosomes are visible as distinct structures only in dividing cells.

Chromatin is a relatively homogeneous substance and appears nearly the same in all parts of a cell.

The DNA molecule in the human nucleus is organized into separate, distinct chromosomes.

The structure of the human chromosome varies with the stage of the cell cycle.

The packaging of DNA into chromosomes is a vital process that ensures efficient replication and segregation of each chromosome into daughter cells during cell division.

The structure of chromosomes is maintained by specialized proteins, which bind to DNA to form nucleosomes.

The number of chromosomes within a given cell is constant throughout the organism's lifespan.

The packaging of DNA into a nucleosome involves the wrapping of DNA around a histone octamer, which consists of eight histone molecules.

Chromatin is only present in the nucleus of a cell.
