Guida verificata passo dopo passo1
Understand that DNA is organized into different structures and regions, each with specific functions.
Recognize that a chromosome is a large structure made of DNA and proteins that contains many genes.
Know that a centromere is the part of a chromosome that links sister chromatids and is important during cell division, but it does not code for traits.
Identify that a ribosome is a cellular organelle responsible for protein synthesis, not a DNA section.
Conclude that the term for a section of DNA that codes for a specific trait is a gene, as genes contain the instructions to produce proteins that determine traits.
