Guida verificata passo dopo passo1
Begin by understanding the structure of DNA. DNA is composed of long chains of nucleotides, which are the building blocks of DNA.
Recognize that chromosomes are structures within cells that contain DNA. Each chromosome is made up of many genes.
Identify that a gene is a specific sequence of nucleotides in DNA that codes for a particular trait. It is the functional unit of heredity.
Understand that alleles are different versions of a gene that can exist due to variations in the nucleotide sequence.
Conclude that the term for the segment of DNA that determines a specific trait in an organism is a gene, as it contains the instructions for building proteins that lead to the expression of traits.
