DNA

Living things are made of millions of tiny self-contained components called cells.
Inside of each cell are long and
complex molecules called DNA. DNA stores information that tells the cells how to
create that living thing. Parts of this information that tell how to make one small
part or characteristic of the living thing – red hair, or blue eyes, or a tendency to be
tall – are known as genes.
Every cell in the same living thing has the same DNA, but only some of it is used
in each cell. For instance, some genes that tell how to make parts of the liver are
switched off in the brain. What genes are used can also change over time. For
instance, a lot of genes are used by a child early in pregnancy that are not used
later.
A living thing has two copies of each gene, one from its mother, and one from its
father. There can be multiple types of each gene, which give different instructions:
one version might cause a person to have blue eyes, another might cause them to
have brown. These different versions are known as alleles of the gene.
Since a living thing has two copies of each gene, it can have two different alleles of
it at the same time. Often, one allele will be dominant, meaning that the living
thing looks and acts as if it had only that one allele. The unexpressed allele is
called recessive. In other cases, you end up with something in between the two
possibilities. In that case, the two alleles are called co-dominant.
Most of the characteristics that you can see in a living thing have multiple genes
that influence them. And many genes have multiple effects on the body, because
their function will not have the same effect in each tissue. The multiple effects of a
single gene is called pleiotropism . The whole set of genes is called the genotype,
and the total effect of genes on the body is called the phenotype. These are key
terms in genetics.
Answer the questions:
1. How can you explain DNA?
2. Do we have the same DNA?
3. What are there inside the cells?
4. How many genes does every living thing have?
5. What facts do you know about DNA?
