Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the relationship between DNA and chromosomes?
A
Chromosomes are made of DNA
B
DNA is made of chromosomes
C
DNA and chromosomes are the same thing.
D
All of the above are correct
Explanation: 

Detailed explanation-1: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Detailed explanation-2: -DNA, genes and chromosomes work together to make you who you are. Chromosomes carry DNA in cells. DNA is responsible for building and maintaining your human structure. Genes are segments of your DNA, which give you physical characteristics that make you unique.

Detailed explanation-3: -Most DNA is found inside the nucleus of a cell, where it forms the chromosomes. Chromosomes have proteins called histones that bind to DNA. DNA has two strands that twist into the shape of a spiral ladder called a helix.

Detailed explanation-4: -Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person’s genes. Genes are contained in chromosomes, which are in the cell nucleus.

Detailed explanation-5: -A chromosome is a long chain of DNA molecules that contains part of all of the genetic material of an organism. DNA is a fundamental molecule that carries the genetic instruction of all living organisms. DNA is packed into chromosomes with the help of special proteins called histones.
