Guida verificata passo dopo passo1
Understand the basic structure of genetic material: DNA is composed of long chains of nucleotides, which are the building blocks of DNA.
Recognize that DNA is organized into larger structures called chromosomes, which contain many genes.
Identify that genes are specific sequences or sections of DNA that carry the instructions for making proteins and thus determine traits.
Differentiate genes from other cellular components: ribosomes are the sites of protein synthesis, not sections of DNA.
Conclude that the small sections of DNA that code for traits are called genes.
