After DNA replciation in Mitosis, a chromosome consists of two identical strands, or chromatids. These strands are then seperated during Anaphase to for the new daughter cells.

DNA are the bricks, a chromosome is the structure made of the bricks, in a very static sense. Looked at another way, DNA are websites, regarding each website as a unit of information. The chromosome is the local Net. Change the websites, you change the local Net. Combine all the Nets, with all that information embodied, and you eventually get...you.

A chromosome is a condensed version of DNA. If DNA in a cell was unwound, it would be very long. Therefore, it needs to be packaged into a smaller shape so that it can fit into the nucleus. So, DNA is wrapped around proteins (known as histones) in order to form a more condensed structure, called a chromosome.

The chromosomes in a cell are tightly-coiled strands of DNA. Before mitosis or meiosis occurs, the chromatin (loose DNA) bundles together so that it can go through the process of DNA replication.

They are both one in the same. Chromosomes are tightly-coiled strands of DNA. Normally the DNA is dissociated in the nuclear envelope and is just called DNA. However, before cell division, DNA becomes visible to the eye (simple light-microscope) in the tightly-coiled chromosomes.

An Introduction to DNA and Chromosomes
A closer look at what makes up the human genome...
--------------------------------------------------------------------------------
Let’s start with the basics of genetics. The word “genome” refers to an organism’s complete set of DNA. The fundamental building block of our genome is the molecule known as DNA. You’ve no doubt heard of DNA many times before – in the news, in movies, on television. Yet in order to understand Huntington’s disease, it is important to gain a good understanding of DNA and how DNA is related to genes. Our goal in this section is to review the basic features of the structure and function of the main molecule of heredity.
What is DNA? ...Making the single strand.
Why is DNA so important?
What are complementary strands? ...Making the double helix.
What are chromosomes?
OK, so what are homologous chromosomes?

The gene is a segment of a chromosome that codes for one protein.
A gene is a linear sequence on the DNA molecule.
DNA must be unwound to be able to be transcribed much like thread must be unwound to be used.

the chromosomes carries the DNA, or DNA is a part of the chromosome
