DNA wraps around proteins called histones to form chromosomes.
Chromosomes are structures composed of DNA and proteins that are found in the nucleus of cells. DNA is coiled around proteins called histones to form chromatin, which further condenses to form chromosomes during cell division. Chromosomes contain the genetic information in the form of DNA that determines an organism's traits.
DNA coils to form chromosomes through a process called supercoiling. This involves the DNA strand wrapping around proteins called histones, which then coil up tightly to create a compact structure known as a chromosome.
DNA is shaped like a double helix. It is stored in cells in the form of chromosomes, which are long strands of DNA wrapped around proteins called histones. These chromosomes are organized in the cell's nucleus.
Chromosomes contain DNA within the cell nucleus.
The network of nuclear threads composed of DNA and protein that condense to form chromosomes during mitosis is called chromatin. Chromatin consists of DNA wrapped around histone proteins, and it undergoes further condensation to form visible chromosomes during cell division.
DNA and proteins, specifically histones, condense together to form chromosomes. DNA molecules wrap around histone proteins to create nucleosomes, which then coil and pack together tightly to form the condensed structure of a chromosome.

Chromosomes are made up of DNA. DNA wraps around proteins called histones to form structures called nucleosomes, which then coil and condense to create chromosomes. Each chromosome contains a single, long DNA molecule.

Yes, chromosomes are composed of DNA molecules wrapped around proteins called histones to form nucleosomes. Nucleosomes, the basic structural units of chromatin, help in compacting and organizing the DNA within the chromosome.
Replication chemicals trigger during cell replication trigger DNA to wrap tightly around histone octamers (histone proteins) to create nucleosomes, for DNA synthesis. This happens during the prophase stage of cell replication.
Chromosomes are mostly made of DNA, which contains the genetic information of an organism. DNA is tightly coiled around proteins called histones to form chromatin, which then condenses into visible chromosomes during cell division.
DNA coils to form chromosomes through a process called supercoiling. This involves the DNA strand wrapping around proteins called histones, which then coil up tightly to create a compact structure known as a chromosome.
Before chromosomes can form, DNA must replicate to ensure that each daughter cell receives a complete set of genetic material during cell division. This process occurs during the S phase of the cell cycle.
The structures in the nucleus that contain DNA are chromosomes. DNA molecules are tightly wound around proteins called histones to form chromatin, which further condenses into chromosomes during cell division. These chromosomes carry the genetic information necessary for cell function and reproduction.
