Guida verificata passo dopo passo1
Understand that DNA is organized into segments that carry hereditary information.
Recall that a nucleotide is the basic building block of DNA, not a segment that codes for traits.
Recognize that a codon is a sequence of three nucleotides that codes for a specific amino acid, but it is smaller than the segment responsible for traits.
Know that a centromere is a region of a chromosome important for chromosome movement during cell division, not for coding traits.
Identify that a gene is the segment of DNA located on a chromosome that contains the instructions to produce a trait.
