Because we have inherited genes from our parents.
2. What are genes?
Definition:
The DNA segments carrying genetic information are called genes.
The scientific study of genes is called genetics.
DNA is a nucleic acid containing the genetic information.
It is in the shape of a transparent twisting ladder.Stem cells are flexible cells that can develop into every other type of cell in the body. Cloning and DNAFast-reading
How many parts can the passage be divided into?
What’s the main idea of each part?
(Para 1 to 2 ) the discovery of the structure of DNA and the further study into it.
(Para 3) how to clone something

1. Define the terms: DNA, clone,enzyme.
DNA is a transparent twisting ladder made of fundamental components of life.
A clone is an organism which is genetically identical to another one.
