Unit 5 Look into ScienceWhat do you have in common with a banana? Even though we might not look alike, all living things—bananas and people included—are made up of the same basic material.Just like houses are made up of smaller units such as bricks, all living things are made up of trillions of microscopic(微观的) building blocks called cells. Within an organism, each cell contains a complete set of “blueprint”. These direc tions determine the organism's characteristics.If we could zoom in(放大) on a single, tiny cell, we could see a “container” inside called a nucleus(细胞核). It holds a stringy substance called DNA, which is like a set of blueprints, or instructions. DNA contains a code for how to build a lifeform and put together the features that make the organism unique. Segments, or pieces, of DNA are called “genes”. In living things, such as us, each gene determines something about our bodies—a trait. In our DNA, there are genes that are responsible for hair colour, eye colour, ear lobe shape and so on. We get our DNA from our parents. Some characteristics, like eye colour, are pretty much entirely determined by DNA.Some are determined both by DNA and by your environment as you grow up, like how tall you will be as an adult. And some traits are not very directly tied to DNA at all, like the kind of books you like to read.Just like us, banana plants have genes and DNA in their cells, and their DNA determines their traits, although we can't see a single cell or the DNA inside of it. If we remove DNA from millions of cells, however, we will be able to view it without a microscope. That is what we will do today!。
