How are DNA and chromosomes related?
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.
How does DNA coil to form chromosomes?
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.
What shape is DNA and how is it stored in cells?
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.
Which structure contains DNA within the cells nucleus?
Chromosomes contain DNA within the cell nucleus.
What are the network of nuclear threads composed of DNA and protein that condense to form chromosomes during mitosis is called?
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.
What consists of DNA and protein condenses to form chromosomes?
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.
What is the process in which homologous chromosomes wrap around each around each and exchange DNA?
crossing over

Does DNA have chromosomes in it or is it the other way around?
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.
What wraps around proteins and then compact to form visible chromosomes?
DNA
What is the process in which homologous chromosomes wrap around each other an exchange DNA?
Crossing over
Do chromosomes include DNA molecules histones and nuclosomes?
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.
How do chromosomes turn into DNA?
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.
What are chromosomes mostly made of?
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.
How does DNA coil to form chromosomes?
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.
What must DNA do Before chromosomes can form?
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.
What structures are in the nucleus that contains DNA?
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.
