What is a GMO?
A GMO is short for ically anism, also known as ically anism, or anism. It carries ic material that has been made in the laboratory and transferred into it by ic engineering.
What is the ic material, and where is it found?
The ic material is DNA (deoxyribonucleic acid). It is usually found in every cell, from anisms that have only one cell, to plants and animals that have many cells, where the cells make up tissues ans. The cell and its constituents can be seen only with the help of increasingly powerful microscopes (see Fig. 1).
Figure 1. From plant to DNA
Inside a cell from a plant or animal, the ic material is enclosed in a partment, the nucleus. It is packaged into pact structures called chromosomes. The totality of all the ic material packaged into chromsomes is the genome. Each species has a different genome. For example, there are 23 pairs of chromosomes in the human
