I. Memory all the new words and expressions. II. Finish the exercises on the textbook.
I. Collect some information about DNA on the internet. II. Talk with your friends about what we have learned today.
Thank You!
It means that when you have a grandson or granddaughter, he or she will have your DNA.
Your DNA has billions of instructions that explain why you are the way you are. It’s one of the most amazing things in the earth!
Question
If we have something wrong with DNA, what will happen? Talk this with your partner.
When you build a house, you use a blueprint. What’s a blueprint?
There are copies of your DNA in every part of your body. For example, your finger has the same DNA with your hair.
You have you own unique DNA, but it repeats patterns from your parents’ DNA. From your DNA, scientists can identify not only you, but also people who are related to you .
In general, a blueprint is a drawing that shows how to put a house together with many different parts. DNA is the blueprint of life.
But building a living thing is far more complex than building a house. It takes millions of years for nature to change the DNA in living things to make them fit the world they live in.
How tall are you? What colour are your eyes? What size are your feet? All these things are strongly influenced by your DNA before you are born!
DNA is fantastic!
