Here's a taster:

Nucleus ~ the central part of an atom. It
contains protons and neutrons, and has
most of the mass of the atom.
Gene ~ the basic unit of genetic material
inherited from our parents. A gene is a
selection of DNA, which controls part of a

Here's a taster:

DNA is the complex chemical that carries genetic
information. DNA is contained in chromosomes,
which are found in the nucleus of most cells. Genes
are units of inheritance and different forms of the
same gene are called alleles.
Cystic fibrosis is an inherited disorder caused by a
faulty allele.
The human genome project has worked out that
the human DNA sequence, and its data can be
useful for forensic science and medical research.…read more

Here's a taster:

Chromosomes are x ­ shaped objects found in the
nucleus of most cells. They consist of long strands
of a substance called deoxyribonucleic acid, or DNA
for short. A section of DNA that has the genetic
code for making a particular protein is called a
The gene is the unit of inheritance, and each
chromosome may have several thousand genes. We
inherit particular chromosomes through the egg of
our mother and sperm of our father. The gene on
those chromosomes carry the code that determines
our physical characteristics, which are a
combination of those of our two parents.…read more
